This set of patches adds the ability to use usb-gpio-connectors with role-switching to the DWC3 controller. Additional Qualcomm specific logic is included in the Qualcomm DWC3 wrapper to facilitate PHY related updates on role-switch and thus VBUS state toggle. These patches have been through seven review cycles already and have a number of Review-by and Ack-by. For the pusposes of making it easier to merge this set focuses on the USB role-switching related stuff alone.
