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 v6: Fixed the review comments from konard.
    - Added the reference voltage in patch 7 for vph-pwr. [Konard]
    - Patches from 1 to 5 of version 5 of the series are accepted.
      So removed from here.

Changes in v4: Fixed review comments from Dmirty, Krzysztof and konard
    - Add only single compatible string in dsi ctrl pattern properties
      in patch 3. [Krzysztof/Dmitry]
    - Move the io_expander RESET and INTR pinctrls from i2c18 node to
      io_expander node in patch 7. [Dmitry]
    - Remove the gpio-hogs from io_expander node, as we are already
      configuring them under anx7625 bridge nodes. [Dmitry/Konard]
    - Updated the commit message based on hpd_enable() and
      hpd_disabled() recommendation in patch 8. [Dmitry]
    - Split the patch 9 of vesrion 3 into two separate patches. [Dmirty]
    - Updated the commit message and commit text in patch 9 and 
      patch 10.

      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]
