-Qualcomm adreno/snapdragon GMU (Graphics management unit)
-
-The GMU is a programmable power controller for the GPU. the CPU controls the
-GMU which in turn handles power controls for the GPU.
-
-Required properties:
-- compatible: "qcom,adreno-gmu-XYZ.W", "qcom,adreno-gmu"
-    for example: "qcom,adreno-gmu-630.2", "qcom,adreno-gmu"
-  Note that you need to list the less specific "qcom,adreno-gmu"
-  for generic matches and the more specific identifier to identify
-  the specific device.
-- reg: Physical base address and length of the GMU registers.
-- reg-names: Matching names for the register regions
-  * "gmu"
-  * "gmu_pdc"
-  * "gmu_pdc_seg"
-- interrupts: The interrupt signals from the GMU.
-- interrupt-names: Matching names for the interrupts
-  * "hfi"
-  * "gmu"
-- clocks: phandles to the device clocks
-- clock-names: Matching names for the clocks
-   * "gmu"
-   * "cxo"
-   * "axi"
-   * "mnoc"
-- power-domains: should be:
-	<&clock_gpucc GPU_CX_GDSC>
-	<&clock_gpucc GPU_GX_GDSC>
-- power-domain-names: Matching names for the power domains
-- iommus: phandle to the adreno iommu
-- operating-points-v2: phandle to the OPP operating points

-

+title: Devicetree bindings for the GMU attached to certain Adreno GPUs
+
+maintainers:
+  - Rob Clark <robdclark@gmail.com>
+
+description: |
+  These bindings describe the Graphics Management Unit (GMU) that is attached
+  to members of the Adreno A6xx GPU family. The GMU provides on-device power
+  management and support to improve power efficiency and reduce the load on
+  the CPU.
