V7: - Adds R/B to "dt-bindings: phy: qcom,sc7180-qmp-usb3-dp-phy: Add input and output ports" - Krzysztof - Fixes indicated, adds R/B to "dt-bindings: usb: Add Qualcomm PMIC Type-C" - Krzysztof - Fixes indicated, adds R/B to "usb: typec: qcom: Add Qualcomm PMIC Type-C driver" - Guenter - Fixes indicated, adds R/B to "usb: typec: qcom: Add Qualcomm PMIC Type-C driver" - Caleb - Adds R/B to "arm64: dts: qcom: sm8250: Define ports for qmpphy orientation-switching" - Konrad - Adds R/B to "arm64: dts: qcom: qrb5165-rb5: Switch on Type-C VBUS boost" - Konrad - Fixes indicated, adds R/B to "arm64: dts: qcom: qrb5165-rb5: Switch on basic TCPM" - Jianhua, Konrad - Connector ports/endpoints left inside of connector Documentation/devicetree/bindings/connector/usb-connector.yaml - Jianhua - dwc3_role_switch_in -> usb_1_dwc3_role_switch_in qmpphy_typec_mux_in -> usb_1_qmpphy_typec_mux_in Both ports/endpoints defined inside of pm8150b dtsi - Konrad I modified the name of both so that the port/endpoint would be directly adjacent to the containing node in the dtsi file for code locality/readbility - bod - Fixes newline indicated "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM usb-role-switching for usb_1" - Jianhua, Konrad - Fixes newline indicated "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM orientation-switch for usb_1_qmpphy" - Jianhua, Konrad - connector I have left the connector defintion and its ports/endpoints in the platform dts The reason for this a) Prior art e.g. arch/arm64/boot/dts/qcom/sc8280xp* b) The connector is really a non-SoC/PMIC component its something that is defined for your platform. I'm open to further debate on this topic: Link: https://imgflip.com/i/7kw6ck - port@1 -> port@1 "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM orientation-switch for usb_1_qmpphy" - Jianhua - OF: graph: no port node found in /soc@0/spmi@c440000/pmic@2/typec@1500 I left this as-is since the DT model we want is to connect the connector directly to the PHY for orientation or controller for data-role switching I similarly didn't put this hack in place to remove the warning but "it would work" &pm8150b_typec { status = "okay";
