    Subject[PATCH v4 4/8] ARM: dts: Add pwm-fan node to the Odroid-U3 board
    Date
    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.

    [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
