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.
This driver also supports devices without DTS specified.
To provide correct functionality, new properties to device tree description for
Exynos4412 and in particular Odroid U3 have been added.
Those patches were tested at Exynos4412 - Odroid U3 board.
Patches were applied on:
linux-soc-thermal/fixes branch (Linux v4.0-rc2)
