   1 Qualcomm adreno/snapdragon GPU
   2
   3 Required properties:
   4 - compatible: "qcom,adreno-XYZ.W", "qcom,adreno" or
   5               "amd,imageon-XYZ.W", "amd,imageon"
   6     for example: "qcom,adreno-306.0", "qcom,adreno"
   7   Note that you need to list the less specific "qcom,adreno" (since this
   8   is what the device is matched on), in addition to the more specific
   9   with the chip-id.
  10   If "amd,imageon" is used, there should be no top level msm device.
  11 - reg: Physical base address and length of the controller's registers.
  12 - interrupts: The interrupt signal from the gpu.
  13 - clocks: device clocks
  14   See ../clocks/clock-bindings.txt for details.
  15 - clock-names: the following clocks are required:
  16   * "core"
  17   * "iface"
  18   * "mem_iface"
  19
