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.
