+    Prefix: 'adt7473'
+    Addresses scanned: I2C 0x2C, 0x2D, 0x2E
+    Datasheet: Publicly available at the Analog Devices website
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7473 chip 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 two (2) voltages. It has three (3) 16-bit counters for
+measuring fan speed. There are three (3) PWM outputs that can be used
+to control fan speed.
+
+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 ADT7473 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 ADT7473 will signal an ALARM if
+any measured value exceeds either limit.
+
+The ADT7473 samples all inputs continuously. The driver will not read
+the registers more often than once every other second. Further,
+configuration data is only read once per minute.
+
+Special Features
+----------------
+
+The ADT7473 have a 10-bit ADC and can therefore measure temperatures
+with 0.25 degC resolution. Temperature readings can be configured either
+for twos complement format or "Offset 64" format, wherein 63 is subtracted
+from the raw value to get the temperature value.
+
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+Hardware Configurations
+-----------------------
+
+The ADT7473 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 the PWM2 function.
+
+Configuration Notes
+-------------------
+
+Besides standard interfaces driver adds the following:
+
+* PWM Control
+
+* pwm#_auto_point1_pwm and pwm#_auto_point1_temp and
+* pwm#_auto_point2_pwm and pwm#_auto_point2_temp -
+
+point1: Set the pwm speed at a lower temperature bound.
+point2: Set the pwm speed at a higher temperature bound.
+
+The ADT7473 will scale the pwm between the lower and higher pwm speed when
+the temperature is between the two temperature boundaries.  PWM values range
+from 0 (off) to 255 (full speed).
+
+Notes
+-----
+
+The NVIDIA binary driver presents an ADT7473 chip via an on-card i2c bus.
+Unfortunately, they fail to set the i2c adapter class, so this driver may
+fail to find the chip until the nvidia driver is patched.

-IDE ATAPI streaming tape driver
--------------------------------
-
-This driver is a part of the Linux ide driver and works in co-operation
-with linux/drivers/block/ide.c.
-
-The driver, in co-operation with ide.c, basically traverses the
-request-list for the block device interface. The character device
-interface, on the other hand, creates new requests, adds them
-to the request-list of the block device, and waits for their completion.
-
-Pipelined operation mode is now supported on both reads and writes.
-
-The block device major and minor numbers are determined from the
-tape's relative position in the ide interfaces, as explained in ide.c.
-
-The character device interface consists of the following devices:
-
- ht0            major 37, minor 0       first  IDE tape, rewind on close.
- ht1            major 37, minor 1       second IDE tape, rewind on close.
- ...
- nht0           major 37, minor 128     first  IDE tape, no rewind on close.
- nht1           major 37, minor 129     second IDE tape, no rewind on close.
- ...
-
-Run /dev/MAKEDEV to create the above entries.
-
-The general magnetic tape commands compatible interface, as defined by
-include/linux/mtio.h, is accessible through the character device.
-
-General ide driver configuration options, such as the interrupt-unmask
-flag, can be configured by issuing an ioctl to the block device interface,
-as any other ide device.
-
-Our own ide-tape ioctl's can be issued to either the block device or
-the character device interface.
-
-Maximal throughput with minimal bus load will usually be achieved in the
-following scenario:
-
-        1.      ide-tape is operating in the pipelined operation mode.
-        2.      No buffering is performed by the user backup program.
