This patch changes the return value of samsung_cmu_register_one()
from 'void type' to 'samsung_clk_provider structure' pointer type because
samsung_clk_provider may be used in each clock driver.

This patch-set uses the samsung_cmu_register_one() function to simplify the
clock driver for Exynos3250/Exynos4415 SoC and change return value of
samsung_cmu_register_one() because some clock driver may need the instance
of samsung_clk_provider structure.

Odroid U3 fan can work without being registered as OF cooling device
(with CONFIG_THERMAL_OF disabled).
In this situation it can be controlled via PWM entry at
/sys/class/hwmon/hwmon0/pwm1.
Therefore, the thermal_of_cooling_device_register() function needs a stub
to allow clean compilation.

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
Several new properties to allow PWM fan working as a cooling device have been

It was necessary to decouple code handling writing to sysfs from the one
responsible for setting PWM of the fan.
Due to that, new __set_pwm() method was extracted, which is responsible for
only setting new PWM duty cycle.
