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 SHA1: d8c3cd75e77d8033b29470525781befc11b6bf7d 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.
