9 title: Devicetree bindings for the GMU attached to certain Adreno GPUs
12 - Rob Clark <robdclark@gmail.com>
15 These bindings describe the Graphics Management Unit (GMU) that is attached
16 to members of the Adreno A6xx GPU family. The GMU provides on-device power
23 - enum:
[all …]
Dgpu.txt1 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
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.
