This describes the interface for the ADT7475 driver:
(there are 4 fans, numbered fan1 to fan4):
fanX_input Read the current speed of the fan (in RPMs)
fanX_min Read/write the minimum speed of the fan. Dropping
below this sets an alarm.
(there are three PWMs, numbered pwm1 to pwm3):
pwmX Read/write the current duty cycle of the PWM. Writes
only have effect when auto mode is turned off (see
below). Range is 0 - 255.
pwmX_enable Fan speed control method:
0 - No control (fan at full speed)
1 - Manual fan speed control (using pwm[1-*])
2 - Automatic fan speed control
pwmX_auto_channels_temp Select which channels affect this PWM
1 - TEMP1 controls PWM
2 - TEMP2 controls PWM
4 - TEMP3 controls PWM
6 - TEMP2 and TEMP3 control PWM
7 - All three inputs control PWM
pwmX_freq Read/write the PWM frequency in Hz. The number
should be one of the following:
11 Hz
14 Hz
22 Hz
29 Hz
35 Hz
44 Hz
58 Hz
88 Hz
pwmX_auto_point1_pwm Read/write the minimum PWM duty cycle in automatic mode
pwmX_auto_point2_pwm Read/write the maximum PWM duty cycle in automatic mode
(there are three temperature settings numbered temp1 to temp3):
tempX_input Read the current temperature. The value is in milli
degrees of Celsius.
tempX_max Read/write the upper temperature limit - exceeding this
will cause an alarm.
tempX_min Read/write the lower temperature limit - exceeding this
will cause an alarm.
tempX_offset Read/write the temperature adjustment offset
tempX_crit Read/write the THERM limit for remote1.
tempX_crit_hyst Set the temperature value below crit where the
fans will stay on - this helps drive the temperature
low enough so it doesn't stay near the edge and
cause THERM to keep tripping.
tempX_auto_point1_temp Read/write the minimum temperature where the fans will
turn on in automatic mode.
tempX_auto_point2_temp Read/write the maximum temperature over which the fans
will run in automatic mode. tempX_auto_point1_temp
and tempX_auto_point2_temp together define the
range of automatic control.
tempX_alarm Read a 1 if the max/min alarm is set
tempX_fault Read a 1 if either temp1 or temp3 diode has a fault
(There are two voltage settings, in1 and in2):
inX_input Read the current voltage on VCC. Value is in
millivolts.
inX_min read/write the minimum voltage limit.
Dropping below this causes an alarm.
inX_max read/write the maximum voltage limit.
Exceeding this causes an alarm.
inX_alarm Read a 1 if the max/min alarm is set.

Description
-----------
This driver implements support for the Analog Devices ADT7473, ADT7475,
ADT7476 and ADT7490 chip family. The ADT7473 and ADT7475 differ only in
minor details. The ADT7476 has additional features, including extra voltage
measurement inputs and VID support. The ADT7490 also has additional
features, including extra voltage measurement inputs and PECI support. All
the supported chips will be collectively designed by the name "ADT747x" in
the rest of this document.
The ADT747x 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) or more 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
ADT747x 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 ADT747x 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 ADT747x will signal an ALARM if
any measured value exceeds either limit.
The ADT747x 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.
Chip Differences Summary
------------------------
ADT7473:
* 2 voltage inputs
* system acoustics optimizations (not implemented)
ADT7475:
* 2 voltage inputs
ADT7476:
* 5 voltage inputs
* VID support
ADT7490:
* 6 voltage inputs
* 1 Imon input (not implemented)
* PECI support (not implemented)
* 2 GPIO pins (not implemented)
* system acoustics optimizations (not implemented)
Special Features
----------------
The ADT747x has a 10-bit ADC and can therefore measure temperatures
with a resolution of 0.25 degree Celsius. Temperature readings can be
configured either for two's complement format or "Offset 64" format,
wherein 64 is subtracted from the raw value to get the temperature value.
The datasheet is very detailed and describes a procedure for determining
an optimal configuration for the automatic PWM control.
Fan Speed Control
-----------------
The driver exposes two trip points per PWM channel.
point1: Set the PWM speed at the lower temperature bound
point2: Set the PWM speed at the higher temperature bound
The ADT747x will scale the PWM linearly between the lower and higher PWM
speed when the temperature is between the two temperature boundaries.
Temperature boundaries are associated to temperature channels rather than
PWM outputs, and a given PWM output can be controlled by several temperature
channels. As a result, the ADT747x may compute more than one PWM value
for a channel at a given time, in which case the maximum value (fastest
fan speed) is applied. PWM values range from 0 (off) to 255 (full speed).
Fan speed may be set to maximum when the temperature sensor associated with
the PWM control exceeds temp#_max.
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.

Description
-----------
The Freescale MC13783 is a Power Management and Audio Circuit. Among
other things it contains a 10-bit A/D converter. The converter has 16
channels which can be used in different modes.
The A/D converter has a resolution of 2.25mV. Channels 0-4 have
a dedicated meaning with chip internal scaling applied. Channels 5-7
can be used as general purpose inputs or alternatively in a dedicated
mode. Channels 12-15 are occupied by the touchscreen if it's active.
Currently the driver only supports channels 2 and 5-15 with no alternative
modes for channels 5-7.
See this table for the meaning of the different channels and their chip
internal scaling:

There is a third case where trip points are associated to both PWM output
channels and temperature channels: the PWM values are associated to PWM
output channels while the temperature values are associated to temperature
channels. In that case, the result is determined by the mapping between
temperature inputs and PWM outputs. When several temperature inputs are
mapped to a given PWM output, this leads to several candidate PWM values.
The actual result is up to the chip, but in general the highest candidate
value (fastest fan speed) wins.

Forcing the address
-------------------
The driver used to have a module parameter named force_addr, which could
be used to force the base I/O address of the hardware monitoring block.
This was meant as a workaround for mainboards with a broken BIOS. This
module parameter is gone for technical reasons. If you need this feature,
you can obtain the same result by using the isaset tool (part of
lm-sensors) before loading the driver:
# Enter the Super I/O config space
isaset -y -f 0x2e 0x87
isaset -y -f 0x2e 0x87
# Select the hwmon logical device
isaset -y 0x2e 0x2f 0x07 0x0b
# Set the base I/O address (to 0x290 in this example)
isaset -y 0x2e 0x2f 0x60 0x02
isaset -y 0x2e 0x2f 0x61 0x90
# Exit the Super-I/O config space
isaset -y -f 0x2e 0xaa
The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
0x4e/0x4f is also possible.
