-Qualcomm adreno/snapdragon GPU
-
-Required properties:
-- 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 (if applicable)
- See ../clocks/clock-bindings.txt for details.
-- clock-names: the following clocks are required by a3xx, a4xx and a5xx
- cores:
- * "core"
- * "iface"
- * "mem_iface"
- For GMU attached devices the GPU clocks are not used and are not required. The
- following devices should not list clocks:
- - qcom,adreno-630.2
-- iommus: optional phandle to an adreno iommu instance
-- operating-points-v2: optional phandle to the OPP operating points
-- interconnects: optional phandle to an interconnect provider. See
- ../interconnect/interconnect.txt for details. Some A3xx and all A4xx platforms
- will have two paths; all others will have one path.
-- interconnect-names: The names of the interconnect paths that correspond to the
- interconnects property. Values must be gfx-mem and ocmem.
-- qcom,gmu: For GMU attached devices a phandle to the GMU device that will
- control the power for the GPU. Applicable targets:
- - qcom,adreno-630.2
-- zap-shader: For a5xx and a6xx devices this node contains a memory-region that
- points to reserved memory to store the zap shader that can be used to help
- bring the GPU out of secure mode.
-- firmware-name: optional property of the 'zap-shader' node, listing the
- relative path of the device specific zap firmware.
-- sram: phandle to the On Chip Memory (OCMEM) that's present on some a3xx and
- a4xx Snapdragon SoCs. See
- Documentation/devicetree/bindings/sram/qcom,ocmem.yaml.
-
-Optional properties:
-- #cooling-cells: The value must be 2. For details, please refer
- Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml.
