Message

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.
