Kernel driver emc2103

Description

-----------
|
||||
|
||||
The Standard Microsystems Corporation (SMSC) EMC2103 chips
|
||||
contain up to 4 temperature sensors and a single fan controller.
|
||||
|
||||
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
|
||||
triggered if the rotation speed has dropped below a programmable limit. Fan
|
||||
readings can be divided by a programmable divider (1, 2, 4 or 8) to give
|
||||
the readings more range or accuracy. Not all RPM values can accurately be
|
||||
represented, so some rounding is done. With a divider of 1, the lowest
|
||||
representable value is 480 RPM.
|
||||
|
||||
This driver supports RPM based control, to use this a fan target
|
||||
should be written to fan1_target and pwm1_enable should be set to 3.
|
||||
|
||||
The 2103-2 and 2103-4 variants have a third temperature sensor, which can
|
||||
be connected to two anti-parallel diodes. These values can be read
|
||||
as temp3 and temp4. If only one diode is attached to this channel, temp4
|
||||
will show as "fault". The module parameter "apd=0" can be used to suppress
|
||||
this 4th channel when anti-parallel diodes are not fitted.

Note 1
|
||||
------
|
||||
|
||||
If you have NOT configured the driver to sample all GPIO pins as analog
|
||||
voltages, then the in10_input and in11_input sysfs attributes will not be
|
||||
created. The driver will sample the GPIO pin that is currently connected to the
|
||||
ADC as an analog voltage, and report the value in in9_input.
|
||||
|
||||
If you have configured the driver to sample all GPIO pins as analog voltages,
|
||||
then they will be sampled in round-robin fashion. If userspace reads too
|
||||
slowly, -EAGAIN will be returned when you read the sysfs attribute containing
|
||||
the sensor reading.
|
||||
|
||||
The LTC4245 chip can be configured to sample all GPIO pins with two methods:
|
||||
1) platform data -- see include/linux/i2c/ltc4245.h
|
||||
2) OF device tree -- add the "ltc4245,use-extra-gpios" property to each chip
|
||||
|
||||
The default mode of operation is to sample a single GPIO pin.

An alarm is triggered if the rotation speed drops below a programmable

limit. Another alarm is triggered if the speed is too low to be measured

(including stalled or missing fan).
|
||||
|
||||
|
||||
Fan Speed Control
|
||||
-----------------
|
||||
|
||||
Fan speed can be controlled by PWM outputs. There are 4 possible modes:
|
||||
always off, always on, manual and automatic. The latter isn't supported
|
||||
by the driver: you can only return to that mode if it was the original
|
||||
setting, and the configuration interface is missing.
|
||||
|
||||
|
||||
Temperature Monitoring
|
||||
----------------------
|
||||
|
||||
The PC87427 relies on external sensors (following the SensorPath
|
||||
standard), so the resolution and range depend on the type of sensor
|
||||
connected. The integer part can be 8-bit or 9-bit, and can be signed or
|
||||
not. I couldn't find a way to figure out the external sensor data
|
||||
temperature format, so user-space adjustment (typically by a factor 2)
|
||||
may be required.
