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"
9   with the chip-id.
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:
22    - qcom,adreno-630.2
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
28 - interconnect-names: The names of the interconnect paths that correspond to the
29   interconnects property. Values must be gfx-mem and ocmem.
30 - qcom,gmu: For GMU attached devices a phandle to the GMU device that will
32     - qcom,adreno-630.2
33 - zap-shader: For a5xx and a6xx devices this node contains a memory-region that
36 - firmware-name: optional property of the 'zap-shader' node, listing the
37   relative path of the device specific zap firmware.
38 - sram: phandle to the On Chip Memory (OCMEM) that's present on some a3xx and
