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 v2: - Add new binding qcom,qcs615-qmp-dp-phy.yaml for QCS615 standalone DP [Krzysztof] - Split DP PHY driver into patches 4-11 by logical chunks [Dmitry][Krzysztof] - 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 (13): dt-bindings: display/msm: Document DP on QCS615 dt-bindings: phy: Add binding for QCS615 standalone QMP DP PHY dt-bindings: phy: qcom,msm8998-qmp-usb3-phy: support dual TCSR registers phy: qcom: qmp-usbc: Rename USB structs and reorganize layout phy: qcom: qmp-usbc: Introduce PHY type enum for USB/DP support phy: qcom: qmp-usbc: Add DP PHY struct definitions phy: qcom: qmp-usbc: Add QCS615 DP PHY configuration and init data phy: qcom: qmp-usbc: Implement DP PHY bring-up flow for QCS615 phy: qcom: qmp-usbc: Wire up DP PHY ops and flow for QCS615 phy: qcom: qmp-usbc: Track PHYs for standalone DP/USB3.0 handling phy: qcom: qmp-usbc: Add QCS615 DP PHY compatible drm/msm/dp: Add DisplayPort support for QCS615 drm/msm/dp: Add support for lane mapping configuration .../bindings/display/msm/dp-controller.yaml | 1 + .../bindings/phy/qcom,msm8998-qmp-usb3-phy.yaml | 28 +- .../bindings/phy/qcom,qcs615-qmp-dp-phy.yaml | 111 ++ 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 | 1466 +++++++++++++++++--- 11 files changed, 1503 insertions(+), 272 deletions(-) --- base-commit: d086c886ceb9f59dea6c3a9dae7eb89e780a20c9 change-id: 20250721-add-displayport-support-for-qcs615-platform-dc5cee522171 Best regards, -- Xiangxu Yin <xiangxu....@oss.qualcomm.com>
