Description
-----------
-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.

motherboard, so the driver assumes that the BIOS set the method
properly.
+Note that the lowest numbered temperature zone trip point corresponds to
+to the border between the highest and one but highest temperature zones, and
+vica versa. So the temperature zone trip points 1-4 (or 1-2) go from high temp
+to low temp! This is how things are implemented in the IC, and the driver
+mimicks this.
+
There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
mode where the actual RPM of the fan (as measured) is controlled and the speed
the Vcore voltage of the processor. The early IT8712F have 5 VID pins,
the IT8716F and late IT8712F have 6. They are shared with other functions
though, so the functionality may not be available on a given system.
-The driver dumbly assume it is there.
The IT8718F and IT8720F also features VID inputs (up to 8 pins) but the value
is stored in the Super-I/O configuration space. Due to technical limitations,

+
+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.

Module Parameters
-----------------
-* force_addr: int
- Initialize the ISA address of the sensors
* force_i2c: int
Initialize the I2C address of the sensors
* init: int
For further information on this driver see the w83781d driver documentation.

+
+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.
