From: Kamil Debski <k.debski@samsung.com>
Add pwm-fan node to the Odroid-U3 board file to enable PWM control of the cooling fan. In addition, add the "pwm" label to the pwm@139D0000 node in the exynos4412.dtsi.
Signed-off-by: Kamil Debski <k.debski@samsung.com> [Rebased on the newest mainline by l.majewski@samsung.com] --- Changes since v1: - added pwm label to the pwm@139D0000 node in exynos4.dtsi - use the pwm label in the exynos4412-odroidu3.dts - change order or properties in the pwn-fan node, to be sorted in alphabetical order
