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.

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.
