+  Use 'init=0' to bypass initializing the chip.
+  Try this if your computer crashes when you load the module.
+
+* force_subclients=bus,caddr,saddr,saddr
+  This is used to force the i2c addresses for subclients of
+  a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
+  to force the subclients of chip 0x2f on bus 0 to i2c addresses
+  0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83792AD/D.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, seven fan rotation speed
+sensors, nine voltage sensors, and two automatic fan regulation
+strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
+Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
+synchronized with selected fan (fan1-fan3). This functionality and manual PWM
+control for fan4-fan7 is not yet implemented.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls 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, 8, 16, 32, 64 or
+128) to give the readings more range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from "realtime status register". Following bits
+are defined:
+
+bit - alarm on:
+0  - in0
+1  - in1
+2  - temp1
+3  - temp2
+4  - temp3
+5  - fan1
+6  - fan2
+7  - fan3
+8  - in2
+9  - in3
+10 - in4
+11 - in5
+12 - in6
+13 - VID change
+14 - chassis
+15 - fan7
+16 - tart1
+17 - tart2
+18 - tart3
+19 - in7
+20 - in8
+21 - fan4
+22 - fan5
+23 - fan6
+
+Tart will be asserted while target temperature cannot be achieved after 3 minutes
+of full speed rotation of corresponding fan.
+
+In addition to the alarms described above, there is a CHAS alarm on the chips
+which triggers if your computer case is open (This one is latched, contrary
+to realtime alarms).
+
+The chips only update values each 3 seconds; reading them more often will
+do no harm, but will return 'old' values.

+W83792D PROBLEMS
+----------------
+Known problems:
+        - This driver is only for Winbond W83792D C version device, there
+          are also some motherboards with B version W83792D device. The
+          calculation method to in6-in7(measured value, limits) is a little
+          different between C and B version. C or B version can be identified
+          by CR[0x49h].
+        - The function of vid and vrm has not been finished, because I'm NOT
+          very familiar with them. Adding support is welcome.
+        - The function of chassis open detection needs more tests.
+        - If you have ASUS server board and chip was not found: Then you will
+          need to upgrade to latest (or beta) BIOS. If it does not help please
+          contact us.
+
+Fan control
+-----------
+
+Manual mode
+-----------
+
+Works as expected. You just need to specify desired PWM/DC value (fan speed)
+in appropriate pwm# file.
+
+Thermal cruise
+--------------
+
+In this mode, W83792D provides the Smart Fan system to automatically control
+fan speed to keep the temperatures of CPU and the system within specific
+range. At first a wanted temperature and interval must be set. This is done
+via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
+interval. The fan speed will be lowered as long as the current temperature
+remains below the thermal_cruise# +- tolerance# value. Once the temperature
+exceeds the high limit (T+tolerance), the fan will be turned on with a
+specific speed set by pwm# and automatically controlled its PWM duty cycle
+with the temperature varying. Three conditions may occur:
+
+(1) If the temperature still exceeds the high limit, PWM duty
+cycle will increase slowly.
+
+(2) If the temperature goes below the high limit, but still above the low
+limit (T-tolerance), the fan speed will be fixed at the current speed because
+the temperature is in the target range.
+
+(3) If the temperature goes below the low limit, PWM duty cycle will decrease
+slowly to 0 or a preset stop value until the temperature exceeds the low
+limit. (The preset stop value handling is not yet implemented in driver)
+
+Smart Fan II
+------------
+
+W83792D also provides a special mode for fan. Four temperature points are
+available. When related temperature sensors detects the temperature in preset
+temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
+on programmed value from sf2_level@_fan#. You need to set four temperatures
+for each fan.

 General Remarks
 ---------------
 
-A typical application will require that the EEPROMs be programmed once and
-never altered afterwards.
+Valid addresses for the MAX6875 are 0x50 and 0x52.
+Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
+The driver does not probe any address, so you must force the address.
+
+Example:
+$ modprobe max6875 force=0,0x50
+
+The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
+addresses.  For example, for address 0x50, it also reserves 0x51.
+The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
+
+
+Programming the chip using i2c-dev
+----------------------------------
+
+Use the i2c-dev interface to access and program the chips.
+Reads and writes are performed differently depending on the address range.
+
+The configuration registers are at addresses 0x00 - 0x45.
+Use i2c_smbus_write_byte_data() to write a register and
+i2c_smbus_read_byte_data() to read a register.
+The command is the register number.
+
+Examples:
+To write a 1 to register 0x45:
+  i2c_smbus_write_byte_data(fd, 0x45, 1);
+
+To read register 0x45:
+  value = i2c_smbus_read_byte_data(fd, 0x45);
+
+
+The configuration EEPROM is at addresses 0x8000 - 0x8045.
+The user EEPROM is at addresses 0x8100 - 0x82ff.
+
+Use i2c_smbus_write_word_data() to write a byte to EEPROM.
+
+The command is the upper byte of the address: 0x80, 0x81, or 0x82.
+The data word is the lower part of the address or'd with data << 8.
+  cmd = address >> 8;
+  val = (address & 0xff) | (data << 8);
+
+Example:
+To write 0x5a to address 0x8003:
+  i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
+
+
+Reading data from the EEPROM is a little more complicated.
+Use i2c_smbus_write_byte_data() to set the read address and then
+i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
+
+Example:
+To read data starting at offset 0x8100, first set the address:
+  i2c_smbus_write_byte_data(fd, 0x81, 0x00);
+
+And then read the data
+  value = i2c_smbus_read_byte(fd);
+
+  or
+
+  count = i2c_smbus_read_i2c_block_data(fd, 0x84, buffer);
+
+The block read should read 16 bytes.
+0x84 is the block read command.
+
+See the datasheet for more details.

-Probing classes (sensors)
--------------------------
-
-If you write a `sensors' driver, you use a slightly different interface.
-As well as I2C addresses, we have to cope with ISA addresses. Also, we
-use a enum of chip types. Don't forget to include `sensors.h'.
-
-The following lists are used internally. They are all lists of integers.
-
-   normal_i2c: filled in by the module writer. Terminated by SENSORS_I2C_END.
-     A list of I2C addresses which should normally be examined.
-   normal_isa: filled in by the module writer. Terminated by SENSORS_ISA_END.
-     A list of ISA addresses which should normally be examined.
-   probe: insmod parameter. Initialize this list with SENSORS_I2C_END values.
-     A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
-     the ISA bus, -1 for any I2C bus), the second is the address. These
-     addresses are also probed, as if they were in the 'normal' list.
-   ignore: insmod parameter. Initialize this list with SENSORS_I2C_END values.
-     A list of pairs. The first value is a bus number (SENSORS_ISA_BUS for
-     the ISA bus, -1 for any I2C bus), the second is the I2C address. These
-     addresses are never probed. This parameter overrules 'normal' and 
-     'probe', but not the 'force' lists.
-
-Also used is a list of pointers to sensors_force_data structures:
-   force_data: insmod parameters. A list, ending with an element of which
-     the force field is NULL.
-     Each element contains the type of chip and a list of pairs.
-     The first value is a bus number (SENSORS_ISA_BUS for the ISA bus, 
-     -1 for any I2C bus), the second is the address. 
-     These are automatically translated to insmod variables of the form
-     force_foo.
-
-So we have a generic insmod variabled `force', and chip-specific variables
-`force_CHIPNAME'.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c' 
-and `normal_isa' parameters, and define what chip names are used. 
-The complete declaration could look like this:
-  /* Scan i2c addresses 0x37, and 0x48 to 0x4f */
-  static unsigned short normal_i2c[] = { 0x37, 0x48, 0x49, 0x4a, 0x4b, 0x4c,

     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.
+    The MAX6875 has a bank of registers and two banks of EEPROM.
+    Address ranges are defined as follows:
+     * 0x0000 - 0x0046 = configuration registers
+     * 0x8000 - 0x8046 = configuration EEPROM
+     * 0x8100 - 0x82FF = user EEPROM
 
-    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
+    This driver makes the user EEPROM available for read.
 
-    In our application, we put device serial & model numbers in user eeprom.
+    The registers & config EEPROM should be accessed via i2c-dev.
 
-    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.
+    The MAX6875 ignores the lowest address bit, so each chip responds to
+    two addresses - 0x50/0x51 and 0x52/0x53.
+
+    Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
+    address, so this driver is destructive if loaded for the wrong EEPROM chip.
