    • “rockchip,rk3399-mali”

• reg : Physical base address of the device and length of the register area.

• interrupts : Contains the three IRQ lines required by Mali Midgard devices.

  provided in the interrupts property. Must contain: “job”, “mmu”, “gpu”.

Optional properties:

• clocks : Phandle to clock for the Mali Midgard device.

• mali-supply : Phandle to regulator for the Mali device. Refer to
  Documentation/devicetree/bindings/regulator/regulator.txt for details.

• operating-points-v2 : Refer to Documentation/devicetree/bindings/opp/opp.txt
