Subject[PATCH v3 0/8] hwmon: thermal: Odroid U3: Provide support for Odroid U3 fan
Date
Presented patches add support for Odroid's U3 optional CPU FAN, which uses PWM
subsystem for low level control.

After successful probe it registers itself as a cooling device for thermal
subsystem. To preserve the ability to use this fan as a PWM device stubs for
thermal_of_cooling_device_register() and thermal_cdev_update() have been added.

Additionally, devices without support for DTS are still supported.

To provide correct functionality, new properties to device tree description for
Exynos4412 and in particular Odroid U3 have been added.

Those patches were tested on Exynos4412 - Odroid U3 board.

Patches were applied on:
linux-soc-thermal/next branch (Linux 3.19-rc5)
SHA1: 252454f5cbda2c6b40c5d36f58cac2938437b85d
