Subject: [PATCH 0/9] hwmon: thermal: Odroid U3: Provide support for Odroid U3
 fan

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 ability to use this fan as a PWM device a stub for
thermal_of_cooling_device_register() has been added.

Moreover, some entries 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
SHA1: c42c7a44c7a543dcb388c1ee1a798e6ed76ad8cf

with following preceding patch series:
'thermal: exynos: Thermal code rework to use device tree'
http://www.spinics.net/lists/linux-samsung-soc/msg37719.html

Presented code utilize reworked Exynos thermal subsystem.
