Subject: [PATCH v5 0/5] Display enablement changes for Qualcomm SA8775P
 platform

This series introduces support to enable the Mobile Display Subsystem (MDSS)
and Display Processing Unit (DPU) for the Qualcomm SA8775P target. It
includes the addition of the hardware catalog, compatible string,
relevant device tree changes, and their YAML bindings.

In this series
- PATCH 1: "dt-bindings: display/msm: Document MDSS on SA8775P" depends on dp
  binding documetion in this change:
  https://lore.kernel.org/all/20240923113150.24711-5-quic_mukhopad@quicinc.com/
- PATCH 5: "arm64: dts: qcom: sa8775p: add display dt nodes for MDSS0 and DPU"
  depends on the clock enablement change:
  https://lore.kernel.org/all/20240816-sa8775p-mm-v3-v1-0-77d53c3c0cef@quicinc.com/

[v5]
- Update clock-name of display-controller in MDSS documentation to align with
  qcom,sm8650-dpu.yaml. [Rob]
- Update power-domains of display-controller in DT to do proper voting on MMCX
  rail. [Internal Review]

[v4]
- Removed new YAML added for sa8775p dpu dt-binding documention as it is similar
  to qcom,sm8650-dpu.yaml and added the compatible in same. [Krzysztof]

[v3]
-Edited copyright for catalog changes. [Dmitry]
-Fix dt_binding_check tool errors(update reg address as address-cells and
 size-cells of root node one and maintain the same for child nodes of mdss,
 added additionalProperties in schema).
 [Rob, Bjorn, Krzysztof]
-Add QCOM_ICC_TAG_ACTIVE_ONLY interconnect path tag to mdp0-mem and mdp1-mem
 path in devicetree. [Dmitry]
-Update commit subject and message for DT change. [Dmitry]
-Remove interconnect path tags from dt bindings. (ref sm8450-mdss yaml)

[v2]
- Updated cover letter subject and message. [Dmitry]
- Use fake DISPCC nodes to avoid clock dependencies in dt-bindings. [Dmitry]
- Update bindings by fixing dt_binding_check tool errors (update includes in example),
  adding proper spacing and indentation in the binding example, droping unused labels,
  droping status disable, adding reset node. [Dmitry, Rob, Krzysztof]
- Reorder compatible string of MDSS and DPU based on alphabetical order.[Dmitry]
- add reg_bus_bw in msm_mdss_data. [Dmitry]
- Fix indentation in the devicetree. [Dmitry]
