Qualcomm adreno/snapdragon GPU
Required properties:
- compatible: "qcom,adreno-XYZ.W", "qcom,adreno"
- compatible: "qcom,adreno-XYZ.W", "qcom,adreno" or
"amd,imageon-XYZ.W", "amd,imageon"
for example: "qcom,adreno-306.0", "qcom,adreno"
Note that you need to list the less specific "qcom,adreno" (since this
is what the device is matched on), in addition to the more specific
with the chip-id.
If "amd,imageon" is used, there should be no top level msm device.
- reg: Physical base address and length of the controller's registers.
- interrupts: The interrupt signal from the gpu.
- clocks: device clocks
