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.
