+
+Description
+-----------
+
+The chips supported by this driver are very similar. The Maxim MAX1617 is
+the oldest; it has the problem that it is not very well detectable. The
+MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
+Ditto for the THMC10. From here on, we will refer to all these chips as
+ADM1021-clones.
+
+The ADM1021 and MAX1617A reports a die code, which is a sort of revision
+code. This can help us pinpoint problems; it is not very useful
+otherwise.
+
+ADM1021-clones implement two temperature sensors. One of them is internal,
+and measures the temperature of the chip itself; the other is external and
+is realised in the form of a transistor-like device. A special alarm
+indicates whether the remote sensor is connected.
+
+Each sensor has its own low and high limits. When they are crossed, the
+corresponding alarm is set and remains on as long as the temperature stays
+out of range. Temperatures are measured in degrees Celsius. Measurements
+are possible between -65 and +127 degrees, with a resolution of one degree.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared!
+
+This driver only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values. It is possible to make
+ADM1021-clones do faster measurements, but there is really no good reason
+for that.
+
+Xeon support
+------------
+
+Some Xeon processors have real max1617, adm1021, or compatible chips
+within them, with two temperature sensors.
+
+Other Xeons have chips with only one sensor.
+
+If you have a Xeon, and the adm1021 module loads, and both temperatures
+appear valid, then things are good.
+
+If the adm1021 module doesn't load, you should try this:
+        modprobe adm1021 force_adm1021=BUS,ADDRESS
+        ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
+
+If you have dual Xeons you may have appear to have two separate
+adm1021-compatible chips, or two single-temperature sensors, at distinct
+addresses.

+Description
+-----------
+
+(This is from Analog Devices.) The ADM1025 is a complete system hardware
+monitor for microprocessor-based systems, providing measurement and limit
+comparison of various system parameters. Five voltage measurement inputs
+are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
+the processor core voltage. The ADM1025 can monitor a sixth power-supply
+voltage by measuring its own VCC. One input (two pins) is dedicated to a
+remote temperature-sensing diode and an on-chip temperature sensor allows
+ambient temperature to be monitored.
+
+One specificity of this chip is that the pin 11 can be hardwired in two
+different manners. It can act as the +12V power-supply voltage analog
+input, or as the a fifth digital entry for the VID reading (bit 4). It's
+kind of strange since both are useful, and the reason for designing the
+chip that way is obscure at least to me. The bit 5 of the configuration
+register can be used to define how the chip is hardwired. Please note that
+it is not a choice you have to make as the user. The choice was already
+made by your motherboard's maker. If the configuration bit isn't set
+properly, you'll have a wrong +12V reading or a wrong VID reading. The way
+the driver handles that is to preserve this bit through the initialization
+process, assuming that the BIOS set it up properly beforehand. If it turns
+out not to be true in some cases, we'll provide a module parameter to force
+modes.
+
+This driver also supports the ADM1025A, which differs from the ADM1025
+only in that it has "open-drain VID inputs while the ADM1025 has on-chip
+100k pull-ups on the VID inputs". It doesn't make any difference for us.

+
+Description
+-----------
+
+This driver implements support for the Analog Devices ADM1026. Analog
+Devices calls it a "complete thermal system management controller."
+
+The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
+16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
+an analog output and a PWM output along with limit, alarm and mask bits for
+all of the above. There is even 8k bytes of EEPROM memory on chip.
+
+Temperatures are measured in degrees Celsius. There are two external
+sensor inputs and one internal sensor. Each sensor has a high and low
+limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
+generated. The interrupts can be masked. In addition, there are over-temp
+limits for each sensor. If this limit is exceeded, the #THERM output will
+be asserted. The current temperature and limits have a resolution of 1
+degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute) but measured
+in counts of a 22.5kHz internal clock. Each fan has a high limit which
+corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
+can be generated. Each fan can be programmed to divide the reference clock
+by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
+rounding is done. With a divider of 8, the slowest measurable speed of a
+two pulse per revolution fan is 661 RPM.
+
+There are 17 voltage sensors. An alarm is triggered if the voltage has
+crossed a programmable minimum or maximum limit. Note that minimum in this
+case always means 'closest to zero'; this is important for negative voltage
+measurements. Several inputs have integrated attenuators so they can measure
+higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
+dedicated inputs. There are several inputs scaled to 0-3V full-scale range
+for SCSI terminator power. The remaining inputs are not scaled and have
+a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
+for negative voltage measurements.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 2.0
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The ADM1026 measures continuously. Analog inputs are measured about 4
+times a second. Fan speed measurement time depends on fan speed and
+divisor. It can take as long as 1.5 seconds to measure all fan speeds.
+
+The ADM1026 has the ability to automatically control fan speed based on the
+temperature sensor inputs. Both the PWM output and the DAC output can be
+used to control fan speed. Usually only one of these two outputs will be
+used. Write the minimum PWM or DAC value to the appropriate control
+register. Then set the low temperature limit in the tmin values for each
+temperature sensor. The range of control is fixed at 20 °C, and the
+largest difference between current and tmin of the temperature sensors sets
+the control output. See the datasheet for several example circuits for
+controlling fan speed with the PWM and DAC outputs. The fan speed sensors
+do not have PWM compensation, so it is probably best to control the fan
+voltage from the power lead rather than on the ground lead.
+
+The datasheet shows an example application with VID signals attached to
+GPIO lines. Unfortunately, the chip may not be connected to the VID lines
+in this way. The driver assumes that the chips *is* connected this way to
+get a VID voltage.

+
+Interface
+---------
+The I2C addresses listed above assume BIOS has not changed the
+chip MSB 5-bit address. Each chip reports a unique manufacturer
+identification code as well as the chip revision/stepping level.
+
+Description
+-----------
+[From ADM9240] The ADM9240 is a complete system hardware monitor for
+microprocessor-based systems, providing measurement and limit comparison
+of up to four power supplies and two processor core voltages, plus
+temperature, two fan speeds and chassis intrusion. Measured values can
+be read out via an I2C-compatible serial System Management Bus, and values
+for limit comparisons can be programmed in over the same serial bus. The
+high speed successive approximation ADC allows frequent sampling of all
+analog channels to ensure a fast interrupt response to any out-of-limit
+measurement.
+
+The ADM9240, DS1780 and LM81 are register compatible, the following
+details are common to the three chips. Chip differences are described
+after this section.
+
+
+Measurements
+------------
+The measurement cycle
+
+The adm9240 driver will take a measurement reading no faster than once
+each two seconds. User-space may read sysfs interface faster than the
+measurement update rate and will receive cached data from the most
+recent measurement.
+
+ADM9240 has a very fast 320us temperature and voltage measurement cycle
+with independent fan speed measurement cycles counting alternating rising
+edges of the fan tacho inputs.
+
+DS1780 measurement cycle is about once per second including fan speed.
+
+LM81 measurement cycle is about once per 400ms including fan speed.
+The LM81 12-bit extended temperature measurement mode is not supported.
+
+Temperature
+-----------
+On chip temperature is reported as degrees Celsius as 9-bit signed data
+with resolution of 0.5 degrees Celsius. High and low temperature limits
+are 8-bit signed data with resolution of one degree Celsius.
+
+Temperature alarm is asserted once the temperature exceeds the high limit,
+and is cleared when the temperature falls below the temp1_max_hyst value.
+
+Fan Speed
+---------
+Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
+clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
+
+rpm = (22500 * 60) / (count * divider)
+
+Automatic fan clock divider
+
+  * User sets 0 to fan_min limit
+    - low speed alarm is disabled
+    - fan clock divider not changed
+    - auto fan clock adjuster enabled for valid fan speed reading
+
+  * User sets fan_min limit too low
+    - low speed alarm is enabled
+    - fan clock divider set to max
+    - fan_min set to register value 254 which corresponds
+      to 664 rpm on adm9240
+    - low speed alarm will be asserted if fan speed is
+      less than minimum measurable speed
+    - auto fan clock adjuster disabled
+
+  * User sets reasonable fan speed
+    - low speed alarm is enabled
+    - fan clock divider set to suit fan_min
+    - auto fan clock adjuster enabled: adjusts fan_min
+
+  * User sets unreasonably high low fan speed limit
+    - resolution of the low speed limit may be reduced
+    - alarm will be asserted
+    - auto fan clock adjuster enabled: adjusts fan_min
+
+    * fan speed may be displayed as zero until the auto fan clock divider
+      adjuster brings fan speed clock divider back into chip measurement
+      range, this will occur within a few measurement cycles.
+
+Analog Output
+-------------
+An analog output provides a 0 to 1.25 volt signal intended for an external
+fan speed amplifier circuit. The analog output is set to maximum value on
+power up or reset. This doesn't do much on the test Intel SE440BX-2.
+
+Voltage Monitor
+
+Voltage (IN) measurement is internally scaled:
+
+    nr  label       nominal     maximum   resolution
+                      mV          mV         mV
+    0   +2.5V        2500        3320       13.0
+    1   Vccp1        2700        3600       14.1
+    2   +3.3V        3300        4380       17.2
+    3     +5V        5000        6640       26.0
+    4    +12V       12000       15940       62.5
+    5   Vccp2        2700        3600       14.1
+
+The reading is an unsigned 8-bit value, nominal voltage measurement is
+represented by a reading of 192, being 3/4 of the measurement range.
+
+An alarm is asserted for any voltage going below or above the set limits.
+
+The driver reports and accepts voltage limits scaled to the above table.
+
+VID Monitor
+-----------
+The chip has five inputs to read the 5-bit VID and reports the mV value
+based on detected CPU type.
+
+Chassis Intrusion
+-----------------
+An alarm is asserted when the CI pin goes active high. The ADM9240
+Datasheet has an example of an external temperature sensor driving
+this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
+connected to a normally open switch.
+
+The ADM9240 provides an internal open drain on this line, and may output
+a 20 ms active low pulse to reset an external Chassis Intrusion latch.
+
+Clear the CI latch by writing value 1 to the sysfs chassis_clear file.

+Kernel driver asb100
+====================
+
+Supported Chips:

+Description
+-----------
+
+This driver implements support for the Asus ASB100 and ASB100-A "Bach".
+These are custom ASICs available only on Asus mainboards. Asus refuses to
+supply a datasheet for these chips. Thanks go to many people who helped
+investigate their hardware, including:
+
+Vitaly V. Bursov
+Alexander van Kaam (author of MBM for Windows)
+Bertrik Sikken
+
+The ASB100 implements seven voltage sensors, three fan rotation speed
+sensors, four temperature sensors, VID lines and alarms. In addition to
+these, the ASB100-A also implements a single PWM controller for fans 2 and
+3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
+controller will simply not work (or maybe it will for you... it doesn't for
+me).
+
+Temperatures are measured and reported in degrees Celsius.
+
+Fan speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit.
+
+Voltage sensors (also known as IN sensors) report values in volts.
+
+The VID lines encode the core voltage value: the voltage level your
+processor should work with. This is hardcoded by the mainboard and/or
+processor itself. It is a value in volts.
+
+Alarms: (TODO question marks indicate may or may not work)
+
+0x0001 => in0 (?)
+0x0002 => in1 (?)
+0x0004 => in2
+0x0008 => in3
+0x0010 => temp1 (1)
+0x0020 => temp2
+0x0040 => fan1
+0x0080 => fan2
+0x0100 => in4

+0x0400 => in6 (?) (2)
+0x0800 => fan3
+0x1000 => chassis switch
+0x2000 => temp3
+
+Alarm Notes:
+
+(1) This alarm will only trigger if the hysteresis value is 127C.
+I.e. it behaves the same as w83781d.
+
+(2) The min and max registers for these values appear to
+be read-only or otherwise stuck at 0x00.
+
+TODO:
+* Experiment with fan divisors > 8.
+* Experiment with temp. sensor types.
+* Are there really 13 voltage inputs? Probably not...
+* Cleanups, no doubt...

+Module Parameters
+------------------
+
+* polarity int
+  Output's polarity: 0 = active high, 1 = active low
+
+Description
+-----------
+
+The DS1621 is a (one instance) digital thermometer and thermostat. It has
+both high and low temperature limits which can be user defined (i.e.
+programmed into non-volatile on-chip registers). Temperature range is -55
+degree Celsius to +125 in 0.5 increments. You may convert this into a
+Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
+parameter is not provided, original value is used.
+
+As for the thermostat, behavior can also be programmed using the polarity
+toggle. On the one hand ("heater"), the thermostat output of the chip,
+Tout, will trigger when the low limit temperature is met or underrun and
+stays high until the high limit is met or exceeded. On the other hand
+("cooler"), vice versa. That way "heater" equals "active low", whereas
+"conditioner" equals "active high". Please note that the DS1621 data sheet
+is somewhat misleading in this point since setting the polarity bit does
+not simply invert Tout.
+
+A second thing is that, during extensive testing, Tout showed a tolerance
+of up to +/- 0.5 degrees even when compared against precise temperature
+readings. Be sure to have a high vs. low temperature limit gap of al least
+1.0 degree Celsius to avoid Tout "bouncing", though!
+
+As for alarms, you can read the alarm status of the DS1621 via the 'alarms'
+/sys file interface. The result consists mainly of bit 6 and 5 of the
+configuration register of the chip; bit 6 (0x40 or 64) is the high alarm
+bit and bit 5 (0x20 or 32) the low one. These bits are set when the high or
+low limits are met or exceeded and are reset by the module as soon as the
+respective temperature ranges are left.
+
+The alarm registers are in no way suitable to find out about the actual
+status of Tout. They will only tell you about its history, whether or not
+any of the limits have ever been met or exceeded since last power-up or
+reset. Be aware: When testing, it showed that the status of Tout can change
+with neither of the alarms set.
+
+Temperature conversion of the DS1621 takes up to 1000ms; internal access to
+non-volatile registers may last for 10ms or below.
+
+High Accuracy Temperature Reading
+---------------------------------
+
+As said before, the temperature issued via the 9-bit i2c-bus data is
+somewhat arbitrary. Internally, the temperature conversion is of a
+different kind that is explained (not so...) well in the DS1621 data sheet.
+To cut the long story short: Inside the DS1621 there are two oscillators,
+both of them biassed by a temperature coefficient.
+
+Higher resolution of the temperature reading can be achieved using the
+internal projection, which means taking account of REG_COUNT and REG_SLOPE
+(the driver manages them):
+
+Taken from Dallas Semiconductors App Note 068: 'Increasing Temperature
+Resolution on the DS1620' and App Note 105: 'High Resolution Temperature
+Measurement with Dallas Direct-to-Digital Temperature Sensors'
+
+- Read the 9-bit temperature and strip the LSB (Truncate the .5 degs)
+- The resulting value is TEMP_READ.
+- Then, read REG_COUNT.
+- And then, REG_SLOPE.
+
+      TEMP = TEMP_READ - 0.25 + ((REG_SLOPE - REG_COUNT) / REG_SLOPE)
+
+Note that this is what the DONE bit in the DS1621 configuration register is
+good for: Internally, one temperature conversion takes up to 1000ms. Before
+that conversion is complete you will not be able to read valid things out
+of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
+tells you whether the conversion is complete ("done", in plain English) and
+thus, whether the values you read are good or not.
+
+The DS1621 has two modes of operation: "Continuous" conversion, which can
+be understood as the default stand-alone mode where the chip gets the
+temperature and controls external devices via its Tout pin or tells other
+i2c's about it if they care. The other mode is called "1SHOT", that means
+that it only figures out about the temperature when it is explicitly told
+to do so; this can be seen as power saving mode.
+
+Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
+the continuous conversions until the contents of these registers are valid,
+or, in 1SHOT mode, you have to have one conversion made.

+Description
+-----------
+
+This is a simple EEPROM module meant to enable reading the first 256 bytes
+of an EEPROM (on a SDRAM DIMM for example). However, it will access serial
+EEPROMs on any I2C adapter. The supported devices are generically called
+24Cxx, and are listed above; however the numbering for these
+industry-standard devices may vary by manufacturer.
+
+This module was a programming exercise to get used to the new project
+organization laid out by Frodo, but it should be at least completely
+effective for decoding the contents of EEPROMs on DIMMs.
+
+DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants.
+The other devices will not be found on a DIMM because they respond to more
+than one address.
+
+DDC Monitors may contain any device. Often a 24C01, which responds to all 8
+addresses, is found.
+
+Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the
+specification, so it is guess work and far from being complete.
+
+The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional
+software write protect register at 0x30 - 0x37 (0x20 less than the memory
+location). The chip responds to "write quick" detection at this address but
+does not respond to byte reads. If this register is present, the lower 128
+bytes of the memory array are not write protected. Any byte data write to
+this address will write protect the memory array permanently, and the
+device will no longer respond at the 0x30-37 address. The eeprom driver
+does not support this register.
+
+Lacking functionality:
+
+* Full support for larger devices (24C04, 24C08, 24C16). These are not
+typically found on a PC. These devices will appear as separate devices at
+multiple addresses.
+
+* Support for really large devices (24C32, 24C64, 24C128, 24C256, 24C512).
+These devices require two-byte address fields and are not supported.
+
+* Enable Writing. Again, no technical reason why not, but making it easy
+to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy
+to disable the DIMMs (potentially preventing the computer from booting)
+until the values are restored somehow.
+
+Use:
+
+After inserting the module (and any other required SMBus/i2c modules), you
+should have some EEPROM directories in /sys/bus/i2c/devices/* of names such
+as "0-0050". Inside each of these is a series of files, the eeprom file
+contains the binary data from EEPROM.

+Kernel driver fscher
+====================
+
+Supported chips:
+  * Fujitsu-Siemens Hermes chip
+    Prefix: 'fscher'
+    Addresses scanned: I2C 0x73
+
+Authors:
+        Reinhard Nissl <rnissl@gmx.de> based on work
+        from Hermann Jung <hej@odn.de>,
+        Frodo Looijaard <frodol@dds.nl>,
+        Philip Edelbrock <phil@netroedge.com>
+
+Description
+-----------
+
+This driver implements support for the Fujitsu-Siemens Hermes chip. It is
+described in the 'Register Set Specification BMC Hermes based Systemboard'
+from Fujitsu-Siemens.
+
+The Hermes chip implements a hardware-based system management, e.g. for
+controlling fan speed and core voltage. There is also a watchdog counter on
+the chip which can trigger an alarm and even shut the system down.
+
+The chip provides three temperature values (CPU, motherboard and
+auxiliary), three voltage values (+12V, +5V and battery) and three fans
+(power supply, CPU and auxiliary).
+
+Temperatures are measured in degrees Celsius. The resolution is 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). The value
+can be divided by a programmable divider (1, 2 or 4) which is stored on
+the chip.
+
+Voltage sensors (also known as "in" sensors) report their values in volts.
+
+All values are reported as final values from the driver. There is no need
+for further calculations.
+
+
+Detailed description
+--------------------
+
+Below you'll find a single line description of all the bit values. With
+this information, you're able to decode e. g. alarms, wdog, etc. To make
+use of the watchdog, you'll need to set the watchdog time and enable the
+watchdog. After that it is necessary to restart the watchdog time within
+the specified period of time, or a system reset will occur.

+
+Limitations
+-----------
+
+* Measuring fan speed
+It seems that the chip counts "ripples" (typical fans produce 2 ripples per
+rotation while VERAX fans produce 18) in a 9-bit register. This register is
+read out every second, then the ripple prescaler (2, 4 or 8) is applied and
+the result is stored in the 8 bit output register. Due to the limitation of
+the counting register to 9 bits, it is impossible to measure a VERAX fan
+properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
+fan produces 1080 ripples per second which causes the counting register to
+overflow twice, leading to only 186 RPM.
+
+* Measuring input voltages
+in2 ("battery") reports the voltage of the onboard lithium battery and not
++3.3V from the power supply.
+
+* Undocumented features
+Fujitsu-Siemens Computers has not documented all features of the chip so
+far. Their software, System Guard, shows that there are a still some
+features which cannot be controlled by this implementation.

+Description
+-----------
+
+IMPORTANT:
+
+For the revision 0x00 chip, the in0, in1, and in2  values (+5V, +3V,
+and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
+
+This driver supports the Genesys Logic GL518SM chip. There are at least
+two revision of this chip, which we call revision 0x00 and 0x80. Revision
+0x80 chips support the reading of all voltages and revision 0x00 only
+for VIN3.
+
+The GL518SM implements one temperature sensor, two fan rotation speed
+sensors, and four voltage sensors. It can report alarms through the
+computer speakers.
+
+Temperatures are measured in degrees Celsius. An alarm goes off while the
+temperature is above the over temperature limit, and has not yet dropped
+below the hysteresis limit. The alarm always reflects the current
+situation. Measurements are guaranteed between -10 degrees and +110
+degrees, with a accuracy of +/-3 degrees.
+
+Rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. In
+case when you have selected to turn fan1 off, no fan1 alarm is triggered.
+
+Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
+give the readings more range or accuracy.  Not all RPM values can
+accurately be represented, so some rounding is done. With a divider
+of 2, the lowest representable value is around 1900 RPM.
+
+Voltage sensors (also known as VIN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. The VDD input
+measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
+volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
+a resolution of 0.019 volt. Note that revision 0x00 chips do not support
+reading the current voltage of any input except for VIN3; limit setting and
+alarms work fine, though.
+
+When an alarm is triggered, you can be warned by a beeping signal through your
+computer speaker. It is possible to enable all beeping globally, or only the
+beeping for some alarms.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once (except for temperature alarms). This means that the
+cause for the alarm may already have disappeared! Note that in the current
+implementation, all hardware registers are read whenever any data is read
+(unless it is less than 1.5 seconds since the last update). This means that
+you can easily miss once-only alarms.
+
+The GL518SM only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+Description
+-----------
+
+This driver implements support for the IT8705F, IT8712F and SiS950 chips.
+
+This driver also supports IT8712F, which adds SMBus access, and a VID
+input, used to report the Vcore voltage of the Pentium processor.
+The IT8712F additionally features VID inputs.
+
+These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
+joysticks and other miscellaneous stuff. For hardware monitoring, they
+include an 'environment controller' with 3 temperature sensors, 3 fan
+rotation speed sensors, 8 voltage sensors, and associated alarms.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give the
+readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt. The battery voltage in8 does not have limit registers.
+
+The VID lines (IT8712F only) encode the core voltage value: the voltage
+level your processor should work with. This is hardcoded by the mainboard
+and/or processor itself. It is a value in volts.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The IT87xx only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+To change sensor N to a thermistor, 'echo 2 > tempN_type' where N is 1, 2,
+or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
+Give 0 for unused sensor. Any other value is invalid. To configure this at
+startup, consult lm_sensors's /etc/sensors.conf. (2 = thermistor;
+3 = thermal diode)
+
+The fan speed control features are limited to manual PWM mode. Automatic
+"Smart Guardian" mode control handling is not implemented. However
+if you want to go for "manual mode" just write 1 to pwmN_enable.

+
+Thanks go to Tyan and especially Alex Buckingham for setting up a remote
+access to their S4882 test platform for this driver.
+  http://www.tyan.com/
+
+Description
+-----------
+
+The LM63 is a digital temperature sensor with integrated fan monitoring
+and control.
+
+The LM63 is basically an LM86 with fan speed monitoring and control
+capabilities added. It misses some of the LM86 features though:
+ - No low limit for local temperature.
+ - No critical limit for local temperature.
+ - Critical limit for remote temperature can be changed only once. We
+   will consider that the critical limit is read-only.
+
+The datasheet isn't very clear about what the tachometer reading is.
+
+An explanation from National Semiconductor: The two lower bits of the read
+value have to be masked out. The value is still 16 bit in width.
+
+All temperature values are given in degrees Celsius. Resolution is 1.0
+degree for the local temperature, 0.125 degree for the remote temperature.
+
+The fan speed is measured using a tachometer. Contrary to most chips which
+store the value in an 8-bit register and have a selectable clock divider
+to make sure that the result will fit in the register, the LM63 uses 16-bit
+value for measuring the speed of the fan. It can measure fan speeds down to
+83 RPM, at least in theory.
+
+Note that the pin used for fan monitoring is shared with an alert out
+function. Depending on how the board designer wanted to use the chip, fan
+speed monitoring will or will not be possible. The proper chip configuration
+is left to the BIOS, and the driver will blindly trust it.
+
+A PWM output can be used to control the speed of the fan. The LM63 has two
+PWM modes: manual and automatic. Automatic mode is not fully implemented yet
+(you cannot define your custom PWM/temperature curve), and mode change isn't
+supported either.
+
+The lm63 driver will not update its values more frequently than every
+second; reading them more often will do no harm, but will return 'old'
+values.

+Description
+-----------
+
+The LM75 implements one temperature sensor. Limits can be set through the
+Overtemperature Shutdown register and Hysteresis register. Each value can be
+set and read to half-degree accuracy.
+An alarm is issued (usually to a connected LM78) when the temperature
+gets higher then the Overtemperature Shutdown value; it stays on until
+the temperature falls below the Hysteresis value.
+All temperatures are in degrees Celsius, and are guaranteed within a
+range of -55 to +125 degrees.
+
+The LM75 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+The LM75 is usually used in combination with LM78-like chips, to measure
+the temperature of the processor(s).
+
+The DS75, DS1775, MAX6625, and MAX6626 are supported as well.
+They are not distinguished from an LM75. While most of these chips
+have three additional bits of accuracy (12 vs. 9 for the LM75),
+the additional bits are not supported. Not only that, but these chips will
+not be detected if not in 9-bit precision mode (use the force parameter if
+needed).
+
+The TCN75 is supported as well, and is not distinguished from an LM75.
+
+The LM75 is essentially an industry standard; there may be other
+LM75 clones not listed here, with or without various enhancements,
+that are supported.
+
+The LM77 is not supported, contrary to what we pretended for a long time.
+Both chips are simply not compatible, value encoding differs.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM78, LM78-J
+and LM79. They are described as 'Microprocessor System Hardware Monitors'.
+
+There is almost no difference between the three supported chips. Functionally,
+the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
+which is used to report the lower voltages newer Pentium processors use.
+From here on, LM7* means either of these three types.
+
+The LM7* implements one temperature sensor, three fan rotation speed sensors,
+seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. Measurements are guaranteed
+between -55 and +125 degrees, with a resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+In addition to the alarms described above, there are a couple of additional
+ones. There is a BTI alarm, which gets triggered when an external chip has
+crossed its limits. Usually, this is connected to all LM75 chips; if at
+least one crosses its limits, this bit gets set. The CHAS alarm triggers
+if your computer case is open. The FIFO alarms should never trigger; it
+indicates an internal error. The SMI_IN alarm indicates some other chip
+has triggered an SMI interrupt. As we do not use SMI interrupts at all,
+this condition usually indicates there is a problem with some other
+device.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The LM7* only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+It is described as a 'Serial Interface ACPI-Compatible Microprocessor
+System Hardware Monitor'.
+
+The LM80 implements one temperature sensor, two fan rotation speed sensors,
+seven voltage sensors, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There are two sets of limits
+which operate independently. When the HOT Temperature Limit is crossed,
+this will cause an alarm that will be reasserted until the temperature
+drops below the HOT Hysteresis. The Overtemperature Shutdown (OS) limits
+should work in the same way (but this must be checked; the datasheet
+is unclear about this). Measurements are guaranteed between -55 and
++125 degrees. The current temperature measurement has a resolution of
+0.0625 degrees; the limits have a resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest

+inputs can measure voltages between 0 and 2.55 volts, with a resolution
+of 0.01 volt.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may

+
+Description
+-----------
+
+The LM83 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to three external diodes. It is compatible
+with many other devices such as the LM84 and all other ADM1021 clones.
+The main difference between the LM83 and the LM84 in that the later can
+only sense the temperature of one external diode.
+
+Using the adm1021 driver for a LM83 should work, but only two temperatures
+will be reported instead of four.
+
+The LM83 is only found on a handful of motherboards. Both a confirmed
+list and an unconfirmed list follow. If you can confirm or infirm the
+fact that any of these motherboards do actually have an LM83, please
+contact us. Note that the LM90 can easily be misdetected as a LM83.
+
+Confirmed motherboards:
+    SBS         P014
+
+Unconfirmed motherboards:
+    Gigabyte    GA-8IK1100
+    Iwill       MPX2
+    Soltek      SL-75DRV5
+
+The driver has been successfully tested by Magnus Forsström, who I'd
+like to thank here. More testers will be of course welcome.
+
+The fact that the LM83 is only scarcely used can be easily explained.
+Most motherboards come with more than just temperature sensors for
+health monitoring. They also have voltage and fan rotation speed
+sensors. This means that temperature-only chips are usually used as
+secondary chips coupled with another chip such as an IT8705F or similar
+chip, which provides more features. Since systems usually need three
+temperature sensors (motherboard, processor, power supply) and primary
+chips provide some temperature sensors, the secondary chip, if needed,
+won't have to handle more than two temperatures. Thus, ADM1021 clones
+are sufficient, and there is no need for a four temperatures sensor
+chip such as the LM83. The only case where using an LM83 would make
+sense is on SMP systems, such as the above-mentioned Iwill MPX2,
+because you want an additional temperature sensor for each additional
+CPU.
+
+On the SBS P014, this is different, since the LM83 is the only hardware
+monitoring chipset. One temperature sensor is used for the motherboard
+(actually measuring the LM83's own temperature), one is used for the
+CPU. The two other sensors must be used to measure the temperature of
+two other points of the motherboard. We suspect these points to be the
+north and south bridges, but this couldn't be confirmed.
+
+All temperature values are given in degrees Celsius. Local temperature
+is given within a range of 0 to +85 degrees. Remote temperatures are
+given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
+accuracy is guaranteed to 3.0 degrees (see the datasheet for more
+details).
+
+Each sensor has its own high limit, but the critical limit is common to
+all four sensors. There is no hysteresis mechanism as found on most
+recent temperature sensors.
+
+The lm83 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM85 and
+compatible chips including the Analog Devices ADM1027, ADT7463 and
+SMSC EMC6D10x chips family.
+
+The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. Using an analog to digital converter it measures three (3)
+temperatures and five (5) voltages. It has four (4) 16-bit counters for
+measuring fan speed. Five (5) digital inputs are provided for sampling the
+VID signals from the processor to the VRM. Lastly, there are three (3) PWM
+outputs that can be used to control fan speed.
+
+The voltage inputs have internal scaling resistors so that the following
+voltage can be measured without external resistors:
+
+  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
+
+The temperatures measured are one internal diode, and two remote diodes.
+Remote 1 is generally the CPU temperature. These inputs are designed to
+measure a thermal diode like the one in a Pentium 4 processor in a socket
+423 or socket 478 package. They can also measure temperature using a
+transistor like the 2N3904.
+
+A sophisticated control system for the PWM outputs is designed into the
+LM85 that allows fan speed to be adjusted automatically based on any of the
+three temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the LM85 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.
+This feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The LM85 will signal an ALARM if any
+measured value exceeds either limit.
+
+The LM85 samples all inputs continuously. The lm85 driver will not read
+the registers more often than once a second. Further, configuration data is
+only read once each 5 minutes. There is twice as much config data as
+measurements, so this would seem to be a worthwhile optimization.
+
+Special Features
+----------------
+
+The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
+Both have special circuitry to compensate for PWM interactions with the
+TACH signal from the fans. The ADM1027 can be configured to measure the
+speed of a two wire fan, but the input conditioning circuitry is different
+for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
+exposed to user control. The BIOS should initialize them to the correct
+mode. If you've designed your own ADM1027, you'll have to modify the
+init_client function and add an insmod parameter to set this up.
+
+To smooth the response of fans to changes in temperature, the LM85 has an
+optional filter for smoothing temperatures. The ADM1027 has the same
+config option but uses it to rate limit the changes to fan speed instead.
+
+The ADM1027 and ADT7463 have a 10-bit ADC and can therefore measure
+temperatures with 0.25 degC resolution. They also provide an offset to the
+temperature readings that is automatically applied during measurement.
+This offset can be used to zero out any errors due to traces and placement.
+The documentation says that the offset is in 0.25 degC steps, but in
+initial testing of the ADM1027 it was 1.00 degC steps. Analog Devices has
+confirmed this "bug". The ADT7463 is reported to work as described in the
+documentation. The current lm85 driver does not show the offset register.
+
+The ADT7463 has a THERM asserted counter. This counter has a 22.76ms
+resolution and a range of 5.8 seconds. The driver implements a 32-bit
+accumulator of the counter value to extend the range to over a year. The
+counter will stay at it's max value until read.
+
+See the vendor datasheets for more information. There is application note
+from National (AN-1260) with some additional information about the LM85.
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
+fan speeds. They use this monitoring capability to alert the system to out
+of limit conditions and can automatically control the speeds of multiple
+fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
+package, and the EMC6D100, available in a 28-pin SSOP package, are designed
+to be register compatible. The EMC6D100 offers all the features of the
+EMC6D101 plus additional voltage monitoring and system control features.
+Unfortunately it is not possible to distinguish between the package
+versions on register level so these additional voltage inputs may read
+zero. The EMC6D102 features addtional ADC bits thus extending precision
+of voltage and temperature channels.
+
+
+Hardware Configurations
+-----------------------
+
+The LM85 can be jumpered for 3 different SMBus addresses. There are
+no other hardware configuration options for the LM85.
+
+The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
+datasheet for a complete description of the differences. Other than
+identifying the chip, the driver behaves no differently with regard to
+these two chips. The LM85B is recommended for new designs.
+
+The ADM1027 and ADT7463 chips have an optional SMBALERT output that can be
+used to signal the chipset in case a limit is exceeded or the temperature
+sensors fail. Individual sensor interrupts can be masked so they won't
+trigger SMBALERT. The SMBALERT output if configured replaces one of the other
+functions (PWM2 or IN0). This functionality is not implemented in current
+driver.
+
+The ADT7463 also has an optional THERM output/input which can be connected
+to the processor PROC_HOT output. If available, the autofan control
+dynamic Tmin feature can be enabled to keep the system temperature within
+spec (just?!) with the least possible fan noise.
+
+Configuration Notes
+-------------------
+
+Besides standard interfaces driver adds following:
+
+* Temperatures and Zones
+
+Each temperature sensor is associated with a Zone. There are three
+sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
+temperature configuration points:
+
+* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
+* temp#_auto_temp_min - temperature over which fans start to spin.
+* temp#_auto_temp_max - temperature when fans spin at full speed.
+* temp#_auto_temp_crit - temperature when all fans will run full speed.
+
+* PWM Control
+
+There are three PWM outputs. The LM85 datasheet suggests that the
+pwm3 output control both fan3 and fan4. Each PWM can be individually
+configured and assigned to a zone for it's control value. Each PWM can be
+configured individually according to the following options.
+
+* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
+                      temperature. (PWM value from 0 to 255)
+
+* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
+                       in range of 10.0 to 94.0 Hz in .1 Hz units.
+                       (Values 100 to 940).
+
+The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
+frequency to a value not on this list, will result in the next higher frequency
+being selected. The actual device frequency may vary slightly from this
+specification as designed by the manufacturer. Consult the datasheet for more
+details. (PWM Frequency values:  100, 150, 230, 300, 380, 470, 620, 940)
+
+* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
+                         the bahaviour of fans. Write 1 to let fans spinning at
+                         pwm#_auto_pwm_min or write 0 to let them off.
+
+NOTE: It has been reported that there is a bug in the LM85 that causes the flag
+to be associated with the zones not the PWMs. This contradicts all the
+published documentation. Setting pwm#_min_ctl in this case actually affects all
+PWMs controlled by zone '#'.
+
+* PWM Controlling Zone selection
+
+* pwm#_auto_channels - controls zone that is associated with PWM
+
+Configuration choices:
+
+   Value     Meaning
+  ------  ------------------------------------------------
+      1    Controlled by Zone 1
+      2    Controlled by Zone 2
+      3    Controlled by Zone 3
+     23    Controlled by higher temp of Zone 2 or 3
+    123    Controlled by highest temp of Zone 1, 2 or 3
+      0    PWM always 0%  (off)
+     -1    PWM always 100%  (full on)
+     -2    Manual control (write to 'pwm#' to set)
+
+The National LM85's have two vendor specific configuration
+features. Tach. mode and Spinup Control. For more details on these,
+see the LM85 datasheet or Application Note AN-1260.
+
+The Analog Devices ADM1027 has several vendor specific enhancements.
+The number of pulses-per-rev of the fans can be set, Tach monitoring
+can be optimized for PWM operation, and an offset can be applied to
+the temperatures to compensate for systemic errors in the
+measurements.
+
+In addition to the ADM1027 features, the ADT7463 also has Tmin control
+and THERM asserted counts. Automatic Tmin control acts to adjust the
+Tmin value to maintain the measured temperature sensor at a specified
+temperature. There isn't much documentation on this feature in the
+ADT7463 data sheet. This is not supported by current driver.

+
+Description
+-----------
+
+This driver implements support for the National Semiconductor LM87.
+
+The LM87 implements up to three temperature sensors, up to two fan
+rotation speed sensors, up to seven voltage sensors, alarms, and some
+miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. Each input has a high
+and low alarm settings. A high limit produces an alarm when the value
+goes above it, and an alarm is also produced when the value goes below
+the low limit.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in
+volts. An alarm is triggered if the voltage has crossed a programmable
+minimum or maximum limit. Note that minimum in this case always means
+'closest to zero'; this is important for negative voltage measurements.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.0 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The lm87 driver only updates its values each 1.0 seconds; reading it more
+often will do no harm, but will return 'old' values.
+
+
+Hardware Configurations
+-----------------------
+
+The LM87 has four pins which can serve one of two possible functions,
+depending on the hardware configuration.
+
+Some functions share pins, so not all functions are available at the same
+time. Which are depends on the hardware setup. This driver assumes that
+the BIOS configured the chip correctly. In that respect, it differs from
+the original driver (from lm_sensors for Linux 2.4), which would force the
+LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
+chipset wiring.
+
+For reference, here is the list of exclusive functions:
+ - in0+in5 (default) or temp3
+ - fan1 (default) or in6
+ - fan2 (default) or in7
+ - VID lines (default) or IRQ lines (not handled by this driver)

+Description
+-----------
+
+The LM90 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to one external diode. It is compatible
+with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
+the MAX6657, MAX6658 and the MAX6659 all of which are supported by this driver.
+Note that there is no easy way to differentiate between the last three
+variants. The extra address and features of the MAX6659 are not supported by
+this driver. Additionally, the ADT7461 is supported if found in ADM1032
+compatibility mode.
+
+The specificity of this family of chipsets over the ADM1021/LM84
+family is that it features critical limits with hysteresis, and an
+increased resolution of the remote temperature measurement.
+
+The different chipsets of the family are not strictly identical, although
+very similar. This driver doesn't handle any specific feature for now,
+but could if there ever was a need for it. For reference, here comes a
+non-exhaustive list of specific features:
+
+LM90:
+  * Filter and alert configuration register at 0xBF.
+  * ALERT is triggered by temperatures over critical limits.
+
+LM86 and LM89:
+  * Same as LM90
+  * Better external channel accuracy
+
+LM99:
+  * Same as LM89
+  * External temperature shifted by 16 degrees down
+
+ADM1032:
+  * Consecutive alert register at 0x22.
+  * Conversion averaging.
+  * Up to 64 conversions/s.
+  * ALERT is triggered by open remote sensor.
+
+ADT7461
+  * Extended temperature range (breaks compatibility)
+  * Lower resolution for remote temperature
+
+MAX6657 and MAX6658:
+  * Remote sensor type selection
+
+MAX6659
+  * Selectable address
+  * Second critical temperature limit
+  * Remote sensor type selection
+
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree for the local temperature, 0.125 degree for the remote
+temperature.
+
+Each sensor has its own high and low limits, plus a critical limit.
+Additionally, there is a relative hysteresis value common to both critical
+values. To make life easier to user-space applications, two absolute values
+are exported, one for each channel, but these values are of course linked.
+Only the local hysteresis can be set from user-space, and the same delta
+applies to the remote hysteresis.
+
+The lm90 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+
+reg_config    - 70 bytes of register space. Any changes take affect immediately.
+
+
+General Remarks
+---------------

+Module Parameters

+
+* init int
+  Chip initialization level:
+   0: None
+  *1: Forcibly enable internal voltage and temperature channels, except in9
+   2: Forcibly enable all voltage and temperature channels, except in9
+   3: Forcibly enable all voltage and temperature channels, including in9
+
+Note that this parameter has no effect for the PC87360, PC87363 and PC87364
+chips.
+
+Also note that for the PC87366, initialization levels 2 and 3 don't enable
+all temperature channels, because some of them share pins with each other,
+so they can't be used at the same time.
+
+
+Description
+-----------
+
+The National Semiconductor PC87360 Super I/O chip contains monitoring and
+PWM control circuitry for two fans. The PC87363 chip is similar, and the
+PC87364 chip has monitoring and PWM control for a third fan.
+
+The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
+hardware monitoring chipsets, not only controlling and monitoring three fans,
+but also monitoring eleven voltage inputs and two (PC87365) or up to four
+(PC87366) temperatures.

+
+The driver assumes that no more than one chip is present, and one of the
+standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
+is triggered if the rotation speed has dropped below a programmable limit.
+A different alarm is triggered if the fan speed is too low to be measured.
+
+Fan readings are affected by a programmable clock divider, giving the
+readings more range or accuracy. Usually, users have to learn how it works,
+but this driver implements dynamic clock divider selection, so you don't
+have to care no more.
+
+For reference, here are a few values about clock dividers:
+
+                slowest         accuracy        highest
+                measurable      around 3000     accurate
+    divider     speed (RPM)     RPM (RPM)       speed (RPM)
+         1        1882              18           6928
+         2         941              37           4898
+         4         470              74           3464
+         8         235             150           2449
+
+For the curious, here is how the values above were computed:
+ * slowest measurable speed: clock/(255*divider)
+ * accuracy around 3000 RPM: 3000^2/clock
+ * highest accurate speed: sqrt(clock*100)
+The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
+RPM as the lowest acceptable accuracy.
+
+As mentioned above, you don't have to care about this no more.
+
+Note that not all RPM values can be represented, even when the best clock
+divider is selected. This is not only true for the measured speeds, but
+also for the programmable low limits, so don't be surprised if you try to
+set, say, fan1_min to 2900 and it finally reads 2909.
+
+
+Fan Control
+-----------
+
+PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
+that the fan is stopped, and 255 meaning that the fan goes at full speed.
+
+Be extremely careful when changing PWM values. Low PWM values, even
+non-zero, can stop the fan, which may cause irreversible damage to your
+hardware if temperature increases too much. When changing PWM values, go
+step by step and keep an eye on temperatures.
+
+One user reported problems with PWM. Changing PWM values would break fan
+speed readings. No explanation nor fix could be found.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in degrees Celsius. Each temperature measured has
+associated low, high and overtemperature limits, each of which triggers an
+alarm when crossed.
+
+The first two temperature channels are external. The third one (PC87366
+only) is internal.
+
+The PC87366 has three additional temperature channels, based on
+thermistors (as opposed to thermal diodes for the first three temperature
+channels). For technical reasons, these channels are held by the VLM
+(voltage level monitor) logical device, not the TMS (temperature
+measurement) one. As a consequence, these temperatures are exported as
+voltages, and converted into temperatures in user-space.
+
+Note that these three additional channels share their pins with the
+external thermal diode channels, so you (physically) can't use them all at
+the same time. Although it should be possible to mix the two sensor types,
+the documents from National Semiconductor suggest that motherboard
+manufacturers should choose one type and stick to it. So you will more
+likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
+thermal diode, and thermistors).
+
+
+Voltage Monitoring
+------------------
+
+Voltages are reported relatively to a reference voltage, either internal or
+external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
+internally, you will have to compensate in sensors.conf. Others (in0 to in6)
+are likely to be divided externally. The meaning of each of these inputs as
+well as the values of the resistors used for division is left to the
+motherboard manufacturers, so you will have to document yourself and edit
+sensors.conf accordingly. National Semiconductor has a document with
+recommended resistor values for some voltages, but this still leaves much
+room for per motherboard specificities, unfortunately. Even worse,
+motherboard manufacturers don't seem to care about National Semiconductor's
+recommendations.
+
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+
+When available, VID inputs are used to provide the nominal CPU Core voltage.
+The driver will default to VRM 9.0, but this can be changed from user-space.
+The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
+the driver will only export one for now. This may change later if there is
+a need.
+
+
+General Remarks
+---------------
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that all hardware registers are read whenever any
+data is read (unless it is less than 2 seconds since the last update, in
+which case cached values are returned instead). As a consequence, when
+a once-only alarm triggers, it may take 2 seconds for it to show, and 2
+more seconds for it to disappear.
+
+Monitoring of in9 isn't enabled at lower init levels (<3) because that
+channel measures the battery voltage (Vbat). It is a known fact that
+repeatedly sampling the battery voltage reduces its lifetime. National
+Semiconductor smartly designed their chipset so that in9 is sampled only
+once every 1024 sampling cycles (that is every 34 minutes at the default
+sampling rate), so the effect is attenuated, but still present.
+
+
+Limitations
+-----------
+
+The datasheets suggests that some values (fan mins, fan dividers)
+shouldn't be changed once the monitoring has started, but we ignore that
+recommendation. We'll reconsider if it actually causes trouble.

+Description
+-----------
+
+The Philips PCA9539 is a 16 bit low power I/O device.
+All 16 lines can be individually configured as an input or output.
+The input sense can also be inverted.
+The 16 lines are split between two bytes.

+
+input reads the actual state of the line and is always available.
+The direction defaults to input for all channels.
+
+
+General Remarks
+---------------
+
+Note that each output, direction, and invert entry controls 8 lines.
+You should use the read, modify, write sequence.

+Description
+-----------
+The PCF8574(A) is an 8-bit I/O expander for the I2C bus produced by Philips
+Semiconductors. It is designed to provide a byte I2C interface to up to 16
+separate devices (8 x PCF8574 and 8 x PCF8574A).
+
+This device consists of a quasi-bidirectional port. Each of the eight I/Os
+can be independently used as an input or output. To setup an I/O as an
+input, you have to write a 1 to the corresponding output.
+
+For more informations see the datasheet.
+
+
+Accessing PCF8574(A) via /sys interface
+-------------------------------------
+
+! Be careful !
+The PCF8574(A) is plainly impossible to detect ! Stupid chip.
+So every chip with address in the interval [20..27] and [38..3f] are
+detected as PCF8574(A). If you have other chips in this address
+range, the workaround is to load this module after the one
+for your others chips.
+
+On detection (i.e. insmod, modprobe et al.), directories are being
+created for each detected PCF8574(A):
+
+/sys/bus/i2c/devices/<0>-<1>/
+where <0> is the bus the chip was detected on (e. g. i2c-0)
+and <1> the chip address ([20..27] or [38..3f]):
+
+(example: /sys/bus/i2c/devices/1-0020/)
+
+Inside these directories, there are two files each:
+read and write (and one file with chip name).
+
+The read file is read-only. Reading gives you the current I/O input
+if the corresponding output is set as 1, otherwise the current output
+value, that is to say 0.
+
+The write file is read/write. Writing a value outputs it on the I/O
+port. Reading returns the last written value.
+
+On module initialization the chip is configured as eight inputs (all
+outputs to 1), so you can connect any circuit to the PCF8574(A) without
+being afraid of short-circuit.

+Description
+-----------
+
+The SiS5595 southbridge has integrated hardware monitor functions. It also
+has an I2C bus, but this driver only supports the hardware monitor. For the
+I2C bus driver see i2c-sis5595.
+
+The SiS5595 implements zero or one temperature sensor, two fan speed
+sensors, four or five voltage sensors, and alarms.
+
+On the first version of the chip, there are four voltage sensors and one
+temperature sensor.
+
+On the second version of the chip, the temperature sensor (temp) and the
+fifth voltage sensor (in4) share a pin which is configurable, but not
+through the driver. Sorry. The driver senses the configuration of the pin,
+which was hopefully set by the BIOS.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the max is crossed; it is also triggered when it drops below the min
+value. Measurements are guaranteed between -55 and +125 degrees, with a
+resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt.
+
+In addition to the alarms described above, there is a BTI alarm, which gets
+triggered when an external chip has crossed its limits. Usually, this is
+connected to some LM75-like chip; if at least one crosses its limits, this
+bit gets set.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The SiS5595 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+Problems
+--------
+Some chips refuse to be enabled. We don't know why.
+The driver will recognize this and print a message in dmesg.

+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
+contain monitoring and PWM control circuitry for two fans.
+
+The 47M15x and 47M192 chips contain a full 'hardware monitoring block'
+in addition to the fan monitoring and control. The hardware monitoring
+block is not supported by the driver.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+PWM values are from 0 to 255.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.

+
+Description
+-----------
+
+The driver does not distinguish between the chips and reports
+all as a 686A.
+
+The Via 686a southbridge has integrated hardware monitor functionality.
+It also has an I2C bus, but this driver only supports the hardware monitor.
+For the I2C bus driver, see <file:Documentation/i2c/busses/i2c-viapro>
+
+The Via 686a implements three temperature sensors, two fan rotation speed
+sensors, five voltage sensors and alarms.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Voltages are internally scalled, so each voltage channel
+has a different resolution and range.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The driver only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+Description
+-----------
+
+This driver implements support for ISA accesses *only* for
+the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
+We will refer to them collectively as Winbond chips.
+
+This driver supports ISA accesses, which should be more reliable
+than i2c accesses. Also, for Tyan boards which contain both a
+Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
+using this driver will avoid i2c address conflicts and complex
+initialization that were required in the w83781d driver.
+
+If you really want i2c accesses for these Super I/O chips,
+use the w83781d driver. However this is not the preferred method
+now that this ISA driver has been developed.
+
+Technically, the w83627thf does not support a VID reading. However, it's
+possible or even likely that your mainboard maker has routed these signals
+to a specific set of general purpose IO pins (the Asus P4C800-E is one such
+board). The w83627thf driver now interprets these as VID. If the VID on
+your board doesn't work, first see doc/vid in the lm_sensors package. If
+that still doesn't help, email us at lm-sensors@lm-sensors.org.
+
+For further information on this driver see the w83781d driver
+documentation.

+
+There is quite some difference between these chips, but they are similar

+
+Detection of these chips can sometimes be foiled because they can be in
+an internal state that allows no clean access. If you know the address
+of the chip, use a 'force' parameter; this will put them into a more
+well-behaved state first.
+
+The W8378* implements temperature sensors (three on the W83781D and W83782D,
+two on the W83783S), three fan rotation speed sensors, voltage sensors
+(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
+lines, alarms with beep warnings, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There is always one main
+temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
+sensors. An alarm is triggered for the main sensor once when the
+Overtemperature Shutdown limit is crossed; it is triggered again as soon as
+it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. The driver sets the
+hysteresis value for temp1 to 127 at initialization.
+
+For the other temperature sensor(s), an alarm is triggered when the
+temperature gets higher then the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value. But on the
+W83781D, there is only one alarm that functions for both other sensors!
+Temperatures are guaranteed within a range of -55 to +125 degrees. The
+main temperature sensors has a resolution of 1 degree; the other sensor(s)
+of 0.5 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8 for the
+W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
+the readings more range or accuracy. Not all RPM values can accurately
+be represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+The W83782D and W83783S temperature conversion machine understands about
+several kinds of temperature probes. You can program the so-called
+beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
+TN3904 transistor, and 3435 the default thermistor value. Other values
+are (not yet) supported.
+
+In addition to the alarms described above, there is a CHAS alarm on the
+chips which triggers if your computer case is open.
+
+When an alarm goes off, you can be warned by a beeping signal through
+your computer speaker. It is possible to enable all beeping globally,
+or only the beeping for some alarms.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The chips only update values each 1.5 seconds; reading them more often
+will do no harm, but will return 'old' values.
+
+AS99127F PROBLEMS
+-----------------
+The as99127f support was developed without the benefit of a datasheet.
+In most cases it is treated as a w83781d (although revision 2 of the
+AS99127F looks more like a w83782d).
+This support will be BETA until a datasheet is released.
+One user has reported problems with fans stopping
+occasionally.
+
+Note that the individual beep bits are inverted from the other chips.
+The driver now takes care of this so that user-space applications
+don't have to know about it.
+
+Known problems:
+        - Problems with diode/thermistor settings (supported?)
+        - One user reports fans stopping under high server load.
+        - Revision 2 seems to have 2 PWM registers but we don't know
+          how to handle them. More details below.
+
+These will not be fixed unless we get a datasheet.
+If you have problems, please lobby Asus to release a datasheet.
+Unfortunately several others have without success.
+Please do not send mail to us asking for better as99127f support.
+We have done the best we can without a datasheet.
+Please do not send mail to the author or the sensors group asking for
+a datasheet or ideas on how to convince Asus. We can't help.

+Asus Clones
+-----------
+
+We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
+Here are some very useful information that were given to us by Alex Van
+Kaam about how to detect these chips, and how to read their values. He
+also gives advice for another Asus chipset, the Mozart-2 (which we
+don't support yet). Thanks Alex!
+I reworded some parts and added personal comments.
+
+# Detection:
+
+AS99127F rev.1, AS99127F rev.2 and ASB100:
+- I2C address range: 0x29 - 0x2F
+- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
+  AS99127F)
+- Which one depends on register 0x4F (manufacturer ID):
+  0x06 or 0x94: ASB100
+  0x12 or 0xC3: AS99127F rev.1
+  0x5C or 0xA3: AS99127F rev.2
+  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
+  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
+  respectively. ATT could stand for Asustek something (although it would be
+  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
+  these codes simply aren't meant to be decoded that way.
+
+Mozart-2:
+- I2C address: 0x77
+- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
+- Of the Mozart there are 3 types:
+  0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
+  0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
+  0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
+  You can handle all 3 the exact same way :)
+
+# Temperature sensors:
+
+ASB100:
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+- sensor 4: register 0x17
+Remark: I noticed that on Intel boards sensor 2 is used for the CPU
+  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
+  either ignored or a socket temperature.
+
+AS99127F (rev.1 and 2 alike):
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
+  would control temp1, bit 3 temp2 and bit 5 temp3.
+
+Mozart-2:
+- sensor 1: register 0x27
+- sensor 2: register 0x13
+
+# Fan sensors:
+
+ASB100, AS99127F (rev.1 and 2 alike):
+- 3 fans, identical to the W83781D
+
+Mozart-2:
+- 2 fans only, 1350000/RPM/div
+- fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
+- fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
+
+# Voltages:
+
+This is where there is a difference between AS99127F rev.1 and 2.
+Remark: The difference is similar to the difference between
+  W83781D and W83782D.

+# PWM
+
+Additional info about PWM on the AS99127F (may apply to other Asus
+chips as well) by Jean Delvare as of 2004-04-09:
+
+AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
+and a temperature sensor type selector at 0x5B (which basically means
+that they swapped registers 0x59 and 0x5B when you compare with Winbond
+chips).
+Revision 1 of the chip also has the temperature sensor type selector at
+0x5B, but PWM registers have no effect.
+
+We don't know exactly how the temperature sensor type selection works.
+Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
+temp3, although it is possible that only the most significant bit matters
+each time. So far, values other than 0 always broke the readings.
+
+PWM registers seem to be split in two parts: bit 7 is a mode selector,
+while the other bits seem to define a value or threshold.
+
+When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
+is below a given limit, the fan runs at low speed. If the value is above
+the limit, the fan runs at full speed. We have no clue as to what the limit
+represents. Note that there seem to be some inertia in this mode, speed
+changes may need some time to trigger. Also, an hysteresis mechanism is
+suspected since walking through all the values increasingly and then
+decreasingly led to slightly different limits.
+
+When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
+would not be significant. If the value is below a given limit, the fan runs
+at full speed, while if it is above the limit it runs at low speed (so this
+is the contrary of the other mode, in a way). Here again, we don't know
+what the limit is supposed to represent.
+
+One remarkable thing is that the fans would only have two or three
+different speeds (transitional states left apart), not a whole range as
+you usually get with PWM.
+
+As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
+fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
+
+Please contact us if you can figure out how it is supposed to work. As
+long as we don't know more, the w83781d driver doesn't handle PWM on
+AS99127F chips at all.
+
+Additional info about PWM on the AS99127F rev.1 by Hector Martin:
+
+I've been fiddling around with the (in)famous 0x59 register and
+found out the following values do work as a form of coarse pwm:
+
+0x80 - seems to turn fans off after some time(1-2 minutes)... might be
+some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
+old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attemp at Qfan
+that was dropped at the BIOS)
+0x81 - off
+0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
+hear the high-pitched PWM sound that motors give off at too-low-pwm.
+0x83 - now they do move. Estimate about 70% speed or so.
+0x84-0x8f - full on
+
+Changing the high nibble doesn't seem to do much except the high bit
+(0x80) must be set for PWM to work, else the current pwm doesn't seem to
+change.
+
+My mobo is an ASUS A7V266-E. This behavior is similar to what I got
+with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
+remember the exact value) would be 70% and higher would be full on.

+Kernel driver w83l785ts
+=======================
+
+Supported chips:
+  * Winbond W83L785TS-S
+    Prefix: 'w83l785ts'
+    Addresses scanned: I2C 0x2e
+    Datasheet: Publicly available at the Winbond USA website
+               http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf
+
+Authors:
+        Jean Delvare <khali@linux-fr.org>
+
+Description
+-----------
+
+The W83L785TS-S is a digital temperature sensor. It senses the
+temperature of a single external diode. The high limit is
+theoretically defined as 85 or 100 degrees C through a combination
+of external resistors, so the user cannot change it. Values seen so
+far suggest that the two possible limits are actually 95 and 110
+degrees C. The datasheet is rather poor and obviously inaccurate
+on several points including this one.
+
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree. See the datasheet for details.
+
+The w83l785ts driver will not update its values more frequently than
+every other second; reading them more often will do no harm, but will
+return 'old' values.
+
+Known Issues
+------------
+
+On some systems (Asus), the BIOS is known to interfere with the driver
+and cause read errors. The driver will retry a given number of times
+(5 by default) and then give up, returning the old value (or 0 if
+there is no old value). It seems to work well enough so that you should
+not notice anything. Thanks to James Bolt for helping test this feature.

+Introduction
+------------
+
+Most mainboards have sensor chips to monitor system health (like temperatures,
+voltages, fans speed). They are often connected through an I2C bus, but some
+are also connected directly through the ISA bus.
+
+The kernel drivers make the data from the sensor chips available in the /sys
+virtual filesystem. Userspace tools are then used to display or set or the
+data in a more friendly manner.
+
+Lm-sensors
+----------
+
+Core set of utilites that will allow you to obtain health information,
+setup monitoring limits etc. You can get them on their homepage
+http://www.lm-sensors.nu/ or as a package from your Linux distribution.
+
+If from website:
+Get lmsensors from project web site. Please note, you need only userspace
+part, so compile with "make user_install" target.
+
+General hints to get things working:
+
+0) get lm-sensors userspace utils
+1) compile all drivers in I2C section as modules in your kernel
+2) run sensors-detect script, it will tell you what modules you need to load.
+3) load them and run "sensors" command, you should see some results.
+4) fix sensors.conf, labels, limits, fan divisors
+5) if any more problems consult FAQ, or documentation
+
+Other utilites
+--------------
+
+If you want some graphical indicators of system health look for applications
+like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
+hardware-monitor
+
+If you are server administrator you can try snmpd or mrtgutils.

+    max6875.c - driver for MAX6874/MAX6875
+
+    Copyright (C) 2005 Ben Gardner <bgardner@wabtec.com>
+
+    Based on i2c/chips/eeprom.c
+
+    The MAX6875 has two EEPROM sections: config and user.
+    At reset, the config EEPROM is read into the registers.
+
+    This driver make 3 binary files available in sysfs:
+      reg_config    - direct access to the registers
+      eeprom_config - acesses configuration eeprom space
+      eeprom_user   - free for application use
+
+    In our application, we put device serial & model numbers in user eeprom.
+
+    Notes:
+      1) The datasheet says that register 0x44 / EEPROM 0x8044 should NOT
+         be overwritten, so the driver explicitly prevents that.
+      2) It's a good idea to keep the config (0x45) locked in config EEPROM.
+         You can temporarily enable config writes by changing register 0x45.
+
