This series aims to extend the USB-C PHY to support DP mode and enable DisplayPort on the Qualcomm QCS615 platform.
The devicetree modification for DisplayPort on QCS615 will be provided in a future patch. Signed-off-by: Xiangxu Yin <xiangxu....@oss.qualcomm.com> --- Changes in v3: - Renamed qcom,qcs615-qmp-dp-phy.yaml in v2 to qcom,qcs615-qmp-dp-phy.yaml in v3 for QCS615 USB3+DP PHY. - Updated patch [v3,02/14] to revise binding title, description, and property order. [Krzysztof] - Updated commit messages in patch [v3,01/14] and [v3,13/14] to reflect the DTSI rename and clarify compatibility. [Krzysztof] - Added USB3+DP mode implementation in patches [v3,003–012], organized in logical chunks. [Dmitry] - Dropped patch [v2,03/13] to maintain full backward compatibility with USBC. - Link to v2: https://lore.kernel.org/all/20250722-add-displayport-support-for-qcs615-platform-v2-0-42b403717...@oss.qualcomm.com/ Changes in v2: - Add new binding qcom,qcs615-qmp-dp-phy.yaml for QCS615 standalone DP - Split DP PHY driver into patches 4-11 by logical chunks [Dmitry] - Update DP PHY configuration flow to align with QMP Combo PHY implementation [Dmitry] - Update all hex values to lowercase [Dmitry] - Remove redundant comments in DP PHY driver [Krzysztof] - Remove invalid USBC type define [Dmitry] - Move lane_map, max_dp_lanes, max_dp_link_rate parsing logic to dp_link [Dmitry] - Add TCSR-based mutex logic for DP and USB PHY coexistence [Dmitry] - Drop patches 6–8 and remove related binding properties as rejected upstream - Link to v1: https://lore.kernel.org/all/20241129-add-displayport-support-for-qcs615-platform-v1-0-09a4338d9...@quicinc.com/ --- Xiangxu Yin (14): dt-bindings: display/msm: dp-controller: Add sm6150 dt-bindings: phy: Add QMP USB3+DP PHY for QCS615 phy: qcom: qmp-usbc: Rename USB-specific ops to prepare for DP support phy: qcom: qmp-usbc: Add USBC PHY type enum phy: qcom: qmp-usbc: Add DP-related fields for USB/DP switchable PHY phy: qcom: qmp-usbc: Add QCS615 DP PHY configuration and init data phy: qcom: qmp-usbc: Move reset and regulator config into PHY cfg phy: qcom: qmp-usbc: Add DP PHY configuration support for QCS615 phy: qcom: qmp-usbc: Add DP PHY ops for USB/DP switchable Type-C PHYs phy: qcom: qmp-usbc: Add TCSR parsing and USB/DP mode mutex handling phy: qcom: qmp-usbc: Finalize USB/DP switchable PHY support phy: qcom: qmp-usbc: Add QCS615 DP PHY compatible drm/msm/dp: Add DisplayPort support for sm6150 drm/msm/dp: Add support for lane mapping configuration .../bindings/display/msm/dp-controller.yaml | 1 + .../bindings/phy/qcom,qcs615-qmp-usb3dp-phy.yaml | 108 ++ drivers/gpu/drm/msm/dp/dp_ctrl.c | 10 +- drivers/gpu/drm/msm/dp/dp_display.c | 1 + drivers/gpu/drm/msm/dp/dp_link.c | 71 ++ drivers/gpu/drm/msm/dp/dp_link.h | 5 + drivers/gpu/drm/msm/dp/dp_panel.c | 78 +- drivers/gpu/drm/msm/dp/dp_panel.h | 3 - drivers/phy/qualcomm/phy-qcom-qmp-dp-phy.h | 1 + drivers/phy/qualcomm/phy-qcom-qmp-usbc.c | 1165 +++++++++++++++++--- 10 files changed, 1234 insertions(+), 209 deletions(-) --- base-commit: 958469723b0df2a5efa229f9c4464c8962c35baf change-id: 20250820-add-displayport-support-for-qcs615-platform-895e4ae0e310 Best regards, -- Xiangxu Yin <xiangxu....@oss.qualcomm.com>
