Kernel driver tc654
===================
Supported chips:
* Microship TC654 and TC655
Prefix: 'tc654'
Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/20001734C.pdf
Authors:
Chris Packham <[email protected]>
Masahiko Iwamoto <[email protected]>
Description
-----------
This driver implements support for the Microchip TC654 and TC655.
The TC654 uses the 2-wire interface compatible with the SMBUS 2.0
specification. The TC654 has two (2) inputs for measuring fan RPM and
one (1) PWM output which can be used for fan control.
Configuration Notes
-------------------
Ordinarily the pwm1_mode ABI is used for controlling the pwm output
mode. However, for this chip the output is always pwm, and the
pwm1_mode determines if the pwm output is controlled via the pwm1 value
or via the Vin analog input.
Setting pwm1_mode to 1 will cause the pwm output to be driven based on
the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be
driven based on the Vin input.

Kernel driver tmp108
====================
Supported chips:
* Texas Instruments TMP108
Prefix: 'tmp108'
Addresses scanned: none
Datasheet: http://www.ti.com/product/tmp108
Author:
John Muir <[email protected]>
Description
-----------
The Texas Instruments TMP108 implements one temperature sensor. An alert pin
can be set when temperatures exceed minimum or maximum values plus or minus a
hysteresis value. (This driver does not support interrupts for the alert pin,
and the device runs in comparator mode.)
The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
operating temperature has a minimum of -55 C and a maximum of +150 C.
Hysteresis values can be set to 0, 1, 2, or 4C.
The TMP108 has a programmable update rate that can select between 8, 4, 1, and
0.5 Hz.
By default the TMP108 reads the temperature continuously. To conserve power,
the TMP108 has a one-shot mode where the device is normally shut-down. When a
one shot is requested the temperature is read, the result can be retrieved,
and then the device is shut down automatically. (This driver only supports
continuous mode.)
The driver provides the common sysfs-interface for temperatures (see
Documentation/hwmon/sysfs-interface under Temperatures).
