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 v4: - Drop patch v3[01/14 & 13/14], will sutbmit new patchsets based mst dt binding series. - Update maintainer of qcom,qcs615-qmp-usb3dp-phy.yaml to myself. - Add missing aux and pipe clocks. [Dmitry] - Drop second TCSR phandle; register offsets are described directly. [Dmitry] - Add USBC PHY series related init_load_uA configs. [Dmitry] - Drop v3[04/14] qmp_phy_usbc_type define and use dp_serdes offsets to confirm DP capability [Dmitry] - Reorganize sub-patches as suggested. - Link to v3: https://lore.kernel.org/all/20250820-add-displayport-support-for-qcs615-platform-v3-0-a43bd25ec...@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 [13/14] to reflect the DTSI rename and clarify compatibility.
