This series enables the support for DSI to DP bridge ports
(labled as DSI0 and DSI1) of the Qualcomm's SA8775P Ride platform.

SA8775P SoC has DSI controller v2.5.1 and DSI PHY v4.2.
The Ride platform is having ANX7625 DSI to DP bridge chip from Analogix.

This patch depends on following series:
https://lore.kernel.org/linux-arm-msm/20250127-dts-qcom-dsi-phy-clocks-v1-0-9d8ddbcb1c7f@linaro.org/
(ARM / arm64: dts: qcom: Use the header with DSI phy clock IDs)

Changes in v3: Fixed review comments from Dmitry and Krzysztof
    - Added qcom,sa8775p-dsi-ctrl compatible based on the set of clocks
      which are associated with it in patch 2. [Krzysztof]
    - Drop the blank line and add contains instead of items in pattern
      properties of dsi ctrl and phy in patch 3. [Krzysztof]
    - Updated the node name from anx7625@58 to bridge@58 for anx7625
      dsi-dp bridge in patch 7. [Dmitry/Krzysztof]
    - Updated endpoint label name for input output ports of analogix bridge chip in patch 7. 
    - Check the DP or eDP confiuration based on the aux node in patch 9. [Dmitry]
    - Link to v2 : https://lore.kernel.org/all/20250311122445.3597100-1-quic_amakhija@quicinc.com/

Changes in v2: Fixed review comments from Rob, konard, Dmitry and Krzysztof
    - Added additionalProperities in dsi and phy patternProperties in patch 3. [Rob's bot]
    - Updated example in qcom,sa8775p-mdss.yaml of patch 3:
        - Added port1 and port2 inside mdss0 ports.
        - Renamed dsi ports from mdss_dsi0_in to mdss0_dsi0_in and mdss_dsi1_in to mdss0_dsi1_in.
    - Updated the init load value for vdds supply of DSI PHY from
      150000uA to 48000uA as per chipset power grid in patch 4. [Dmitry]
    - Updated the init load value for vdda supply for DSI ctrl
      from 30100uA to 8300uA as per chipset power grid in patch 5.[Dmitry]
    - Rebase the series to use the header with DSI phy clock IDs to make code more
      readable in patch 6. [konard]
    - Added the interrupts-extended in patch 7. [konard]
    - Fixed the warning from DT checker against DT binding in patch 7. [Krzysztof]
    - Changed the connector node name from dsi0-connector to dp-dsi0-connector and dsi1-connector to dp-dsi1-connector
      respectively in patch 7. [Dmitry]
    - Added the vph_pwr for anx7625 vdda10, vdds18 and vdda33 supply to fix the warnings from DT checker in
      patch 7. [Rob's bot]
    - Addressed device tree comments in patch 7. [Konard]
    - Squash the DT patch 8 into DT patch 7. [Dmitry]
    - Added hpd_enable() and hpd_disable() bridge funcs in patch 9. [Dmitry]
    - Update hpd detection bridge op flags logic based on eDP connector in patch 10. [Dmitry]
    - Link to v1 : https://lore.kernel.org/linux-arm-msm/20250225121824.3869719-1-quic_amakhija@quicinc.com/
