Subject: [PATCH v4 0/5] Add DSI display support for QCS8300 target

This series enables the support for DSI to DP bridge port
(labeled as DSI0) of the Qualcomm's QCS8300 Ride platform.

QCS8300 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/all/20251117-dts_qcs8300-v7-0-bf42d39e7828@oss.qualcomm.com/
(Enable DPU and Display Port for Qualcomm QCS8300-ride platform)

Changes in v4: Addressed review comments from konard and Krzysztof
   - Patch 1: Update commit description to clarify PHY compatible string
              details.[Krzysztof]
   - Patch 2: Update commit description to clarify CTRL compatible string
              details.
   - Patch 4: Added new lines at few places. [konard]
   - Patch 5: 
            - Moved regulator always-on and boot-on properties at the end of
              the node. [konard]
            - Added new lines at few places. [konard]
            - Made the tlmm gpios entries sorted based on gpio index
              number. [Konard]
            - Drop output-high property. [konard]
   - Link to v3 :
     https://lore.kernel.org/all/20251125013302.3835909-1-quic_amakhija@quicinc.com/

Changes in v3: Addressed review comments from konard and Dmitry
   - Patch 2: Remove qcom,qcs8300-dsi-ctrl from clk details. [Dmitry]
   - Remove PHY and CTRL driver support. The CTRL and PHY versions for
     Monaco are the same as LeMans, and Monaco will use the same CTRL
     and PHY based on the fallback compatible string [Dmitry/Konard]
   - Patch 5: Rename the regulator used and arrange the compatible, reg,
     address and size cell for i2cmux in proper order. [Dmitry]
   - Link to v2:
     https://lore.kernel.org/all/20251006013924.1114833-1-quic_amakhija@quicinc.com/

Changes in v2: Addressed review comments from Konard and Dmitry
   - Patch 1: Documented the qcom,qcs8300-dsi-phy-5nm compatible string.
   - Patch 2: Documented the qcom,qcs8300-dsi-ctrl compatible string.
   - Patch 3:
           - Added qcom,qcs8300-dsi-ctrl and qcom,qcs8300-dsi-phy-5nm
             compatible strings
             to the Device Tree bindings. [Dmitry/Konard]
           - Fixed indentation issue. [Dmitry]
           - Drop the extra empty line. [Dmitry]
   - Patch 4: Added PHY driver support for qcom,qcs8300-dsi-phy-5nm.
   - Patch 5: Added CTRL driver support for qcom,qcs8300-dsi-ctrl.
   - Patch 6: Included qcom,qcs8300-dsi-ctrl and
     qcom,qcs8300-dsi-phy-5nm
              compatible strings in the Device Tree. [Dmitry/Konard]
