hwmon: (ntc_thermistor) Add ntc thermistor to thermal subsystem as a sensor.

2014-09-22T18:14:52+00:00

To get more comprehensive and integrated thermal management, it adds ntc
thermistor to thermal framework as a thermal sensor. It's governed thermal
susbsystem only if it is described in DT node. Otherwise, it just notifies
temperature to userspace via sysfs as it used to be.

hwmon: Add pwm-fan driver

2014-08-04T14:01:38+00:00

The pwm-fan driver enables control of fans connected to PWM lines.
This driver uses the PWM framework, so it is compatible with all
PWM devices that provide drivers through the PWM framework.

hwmon: (powerpc/powernv) hwmon driver for power, fan rpm, voltage and temperature

2014-08-04T14:01:38+00:00

This patch adds basic kernel support for reading power values, fan
speed rpm, voltage and temperature data on powernv platforms which
will be exported to user space through sysfs interface.

hwmon: (ntc_thermistor) Use the manufacturer name properly

2014-06-25T14:09:13+00:00

Murata Manufacturing Co., Ltd is the vendor for
NTC (Negative Temperature coefficient) based Thermistors.
But, the driver extensively uses "NTC" as the vendor name.

This patch corrects the vendor name also updates the
compatibility strings according to the vendor-prefix.txt

Note: Drivers continue to support the previous compatible strings
but further addition of these compatible strings in device tree
is deprecated.

Add support for GMT G762/G763 PWM fan controllers

2013-06-27T17:31:42+00:00

GMT G762/763 fan speed PWM controller is connected directly to a fan
and performs closed-loop or open-loop control of the fan speed. Two
modes - PWM or DC - are supported by the chip. Introduced driver
provides various knobs to control the operations of the chip (via
sysfs interface). Specific characteristics of the system can be passed
either using board init code or via DT. Documentation for both the
driver and DT bindings are also provided.

hwmon: (ntc_thermistor) Add DT with IIO support to NTC thermistor driver

2013-04-08T04:16:38+00:00

This patch adds DT support to NTC driver to parse the
platform data.

Also adds the support to work as an iio device client.

During the probe ntc driver gets the respective channels of ADC
and uses iio_raw_read calls to get the ADC converted value.
