This driver implements support for the Analog Devices ADT7473 chip family.
The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
The ADT7473 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
temperatures and two (2) voltages. It has four (4) 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
ADT7473 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.

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.
