ARM: dts: Add pwm-fan node to the Odroid-U3 board
Lukasz Majewski (7):
thermal: Provide stub for thermal_of_cooling_device_register
This patch provides code for reading PWM FAN configuration data via
device tree. The pwm-fan can work with full speed when configuration
is not provided. However, errors are propagated when wrong DT bindings
are found.
Additionally the struct pwm_fan_ctx has been extended.

The PWM FAN device can now be used as a thermal cooling device. Necessary
infrastructure has been added in this commit.

Hi Eduardo,
The exynos_tmu_data() function should on entrance test not only for
valid data pointer, but also for data-tmu_read one.
It is important, since afterwards it is dereferenced to get
temperature code.

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.
