1 Qualcomm adreno/snapdragon GPU
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
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 (if applicable)
14 See ../clocks/clock-bindings.txt for details.
15 - clock-names: the following clocks are required by a3xx, a4xx and a5xx
20 For GMU attached devices the GPU clocks are not used and are not required. The
21 following devices should not list clocks:
23 - iommus: optional phandle to an adreno iommu instance
24 - operating-points-v2: optional phandle to the OPP operating points
25 - interconnects: optional phandle to an interconnect provider. See
26 ../interconnect/interconnect.txt for details.
27 - qcom,gmu: For GMU attached devices a phandle to the GMU device that will
28 control the power for the GPU. Applicable targets:
30 - zap-shader: For a5xx and a6xx devices this node contains a memory-region that
31 points to reserved memory to store the zap shader that can be used to help
32 bring the GPU out of secure mode.
