    Subject[PATCH v4 2/5] arm64: dts: rockchip: Add powerzones definition for rock960
    Date
    Add the powerzones description. This first step introduces the big,
    the little as powerzone places.

    V4:
    - Added missing powerzone-cells
    - Changed powerzone name to comply with the pattern property
    V3:
    - Remove GPU section as no power is available (yet)
    - Remove '#powerzone-cells' conforming to the bindings change
    V2:
    - Move description in the SoC dtsi specific file
    V1: Initial post
