Subject: [PATCH v3 1/2] dt-bindings: display: msm: Convert GMU bindings to YAML
Date:   Mon,  2 Mar 2020 11:23:43 -0700
Message-Id: <1583173424-21832-2-git-send-email-jcrouse@codeaurora.org>
In-Reply-To: <1583173424-21832-1-git-send-email-jcrouse@codeaurora.org>
References: <1583173424-21832-1-git-send-email-jcrouse@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Convert display/msm/gmu.txt to display/msm/gmu.yaml and remove the old
text bindings.

-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
-
-Optional properties:
-- sram: phandle to the On Chip Memory (OCMEM) that's present on some Snapdragon
-        SoCs. See Documentation/devicetree/bindings/sram/qcom,ocmem.yaml.

+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.
