    Subject[PATCH AUTOSEL 4.14 69/87] arm: dts: mediatek: Add missing cooling device properties for CPUs
    Date
    From: Viresh Kumar <viresh.kumar@linaro.org>

    [ Upstream commit 0c7f7a5150023f3c6f0b27c4d4940ce3dfaf62cc ]

    The cooling device properties, like "#cooling-cells" and
    "dynamic-power-coefficient", should either be present for all the CPUs
    of a cluster or none. If these are present only for a subset of CPUs of
    a cluster then things will start falling apart as soon as the CPUs are
    brought online in a different order. For example, this will happen
    because the operating system looks for such properties in the CPU node
    it is trying to bring up, so that it can register a cooling device.

    Add such missing properties.
