    Subject[PATCH 4.14 048/159] arm64: dts: add #cooling-cells to CPU nodes
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Arnd Bergmann <arnd@arndb.de>

    commit acbf76ee05067c3942852019993f7beb69a0f45f upstream.

    dtc complains about the lack of #coolin-cells properties for the
    CPU nodes that are referred to as "cooling-device":

    arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@0 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@0:cooling-device[0])
    arch/arm64/boot/dts/mediatek/mt8173-evb.dtb: Warning (cooling_device_property): Missing property '#cooling-cells' in node /cpus/cpu@100 or bad phandle (referred from /thermal-zones/cpu_thermal/cooling-maps/map@1:cooling-device[0])

    Apparently this property must be '<2>' to match the binding.
