The series takes in a number of patches worked on by a number of people over the past few years from downstream, through to previous upstream submissions for both of these interfaces. Additional work has been done to enable USB role-switching. 1. USB SS - extcon has been dropped in favour of gpio-usb-conn as discussed and agreed previously by Jorge, Bjorn, Stephen Boyd and Jack Pham [1]. - Regulator API has been updated following suggestions from Bjorn. - Sanitzation of the DT compatible name - dropped "snps" entirely from the name - it made almost no sense to me and doesn't appear consistent with similar naming conventions for Snopsys based IP. 2. USB HS - Regulator API changes here. - Dropped "snps" from the namespace for similar reasons as above. - Dropped "28nm" from the namespace, looked superfluous. - Changed "High-Speed" to "Hi-Speed". - [2] 3. DWC3 Role switching - At the time usb-gpio-conn was discussed it was mentioned that role-switching was absent from the DWC3 driver. - John Stultz has some patches in-flight for that, that I've included in this series for completeness. - Adds my SoB to relevant patches. - Drops gerrit ChangeId. 4. DWC3 usb-gpio-conn Needs to be a child node of the DWC3 driver so some code and DT binding is required for that. 5. QCOM-DWC3 Since we are role-switching with an external PMIC supplying VBUS we want to skip past toggling VBUS from QCOM-DWC3 controlled registers, so a patch is added to the qcom-dwc3 driver to do that.

Looking at available data usb-hs-28nm - There are two possible PHYs on 28nm litho node so it makes sense to name the PHY relating to its relevant litho node. usb-ss - This is not litho node dependent and is used on multiple SoCs and litho nodes. - Drop default mode for role switching - Felipe Balbi Felipe asked if the default mode for role switching was required and the answer is no. It makes no difference becuase the USB ID pin ultimately dictates the mode of operation. - Change "gpio_usb_connector" to "connector" - Rob This was a minor change in terms of DTS but, means I need to look for the DTS compatible string as opposed to a label given in the DTS. No matter what the name of the label, this is he right thing to do. - Used IS_ENABLED() - Felipe The logic is the same but IS_ENABLED() is used now. - Retained example of USB connector in dwc.txt - Rob, Felipe Rob pointed out adding the connector was redundant as the documentation already implies it. Felipe seemed in favour of I think adding the example. I've dropped the documentation of the connector and kept the example. https://lore.kernel.org/linux-arm-msm/20200122185610.131930-7-bryan.odonoghue@linaro.org/ - Added example of usb-role-switch in dwc3.txt - BOD - Incorporated various inputs from Rob on DTS/YAML - Added required: - Added additionalProperties: - Renamed "phy" clock to "ahb" - maxItems dropped as indicated Bjorn Andersson (1): arm64: dts: qcom: qcs404: Add USB devices and PHYs Bryan O'Donoghue (11): dt-bindings: usb: dwc3: Add a gpio-usb-connector example dt-bindings: usb: dwc3: Add a usb-role-switch to the example usb: dwc3: qcom: Override VBUS when using gpio_usb_connector usb: dwc3: Add support for usb-conn-gpio connectors arm64: dts: qcom: qcs404-evb: Define VBUS detect pin arm64: dts: qcom: qcs404-evb: Define VBUS boost pin arm64: dts: qcom: qcs404-evb: Define USB ID pin arm64: dts: qcom: qcs404-evb: Describe external VBUS regulator arm64: dts: qcom: qcs404-evb: Raise vreg_l12_3p3 minimum voltage arm64: dts: qcom: qcs404-evb: Enable secondary USB controller arm64: dts: qcom: qcs404-evb: Enable primary USB controller Jorge Ramirez-Ortiz (3): dt-bindings: phy: remove qcom-dwc3-usb-phy dt-bindings: Add Qualcomm USB SuperSpeed PHY bindings phy: qualcomm: usb: Add SuperSpeed PHY driver Shawn Guo (1): phy: qualcomm: Add Synopsys 28nm Hi-Speed USB PHY driver Sriharsha Allenki (1): dt-bindings: phy: Add Qualcomm Synopsys Hi-Speed USB PHY binding Yu Chen (1): usb: dwc3: Registering a role switch in the DRD code. .../bindings/phy/qcom,usb-hs-28nm.yaml | 90 ++++ .../devicetree/bindings/phy/qcom,usb-ss.yaml | 83 ++++ .../bindings/phy/qcom-dwc3-usb-phy.txt | 37 -- .../devicetree/bindings/usb/dwc3.txt | 9 + arch/arm64/boot/dts/qcom/qcs404-evb.dtsi | 90 +++- arch/arm64/boot/dts/qcom/qcs404.dtsi | 100 +++++ drivers/phy/qualcomm/Kconfig | 20 + drivers/phy/qualcomm/Makefile | 2 + drivers/phy/qualcomm/phy-qcom-usb-hs-28nm.c | 415 ++++++++++++++++++ drivers/phy/qualcomm/phy-qcom-usb-ss.c | 246 +++++++++++ drivers/usb/dwc3/core.h | 3 + drivers/usb/dwc3/drd.c | 100 ++++- drivers/usb/dwc3/dwc3-qcom.c | 22 +- 13 files changed, 1175 insertions(+), 42 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/qcom,usb-hs-28nm.yaml create mode 100644 Documentation/devicetree/bindings/phy/qcom,usb-ss.yaml delete mode 100644 Documentation/devicetree/bindings/phy/qcom-dwc3-usb-phy.txt create mode 100644 drivers/phy/qualcomm/phy-qcom-usb-hs-28nm.c create mode 100644 drivers/phy/qualcomm/phy-qcom-usb-ss.c
