+Kernel driver adt7470
+=====================
+
+Supported chips:
+  * Analog Devices ADT7470
+    Prefix: 'adt7470'
+    Addresses scanned: I2C 0x2C, 0x2E, 0x2F
+    Datasheet: Publicly available at the Analog Devices website
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7470 chip.  There may
+be other chips that implement this interface.
+
+The ADT7470 uses the 2-wire interface compatible with the SMBus 2.0
+specification. Using an analog to digital converter it measures up to ten (10)
+external temperatures. It has four (4) 16-bit counters for measuring fan speed.
+There are four (4) PWM outputs that can be used to control fan speed.
+
+A sophisticated control system for the PWM outputs is designed into the ADT7470
+that allows fan speed to be adjusted automatically based on any of the ten
+temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the ADT7470 will adjust the PWM outputs in
+response to the measured temperatures with further host intervention.  This
+feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (temperature, fan speed) has corresponding high/low
+limit values. The ADT7470 will signal an ALARM if any measured value exceeds
+either limit.
+
+The ADT7470 DOES NOT sample all inputs continuously.  A single pin on the
+ADT7470 is connected to a multitude of thermal diodes, but the chip must be
+instructed explicitly to read the multitude of diodes.  If you want to use
+automatic fan control mode, you must manually read any of the temperature
+sensors or the fan control algorithm will not run.  The chip WILL NOT DO THIS
+AUTOMATICALLY; this must be done from userspace.  This may be a bug in the chip
+design, given that many other AD chips take care of this.  The driver will not
+read the registers more often than once every 5 seconds.  Further,
+configuration data is only read once per minute.
+
+Special Features
+----------------
+
+The ADT7470 has a 8-bit ADC and is capable of measuring temperatures with 1
+degC resolution.
+
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+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 ADT7470 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).  Fan speed will be set to maximum when the
+temperature sensor associated with the PWM control exceeds
+pwm#_auto_point2_temp.
+
+Notes
+-----
+
+As stated above, the temperature inputs must be read periodically from
+userspace in order for the automatic pwm algorithm to run.

 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,
