Hi Tony,
Dual role support for DWC3 is now in usb/next. With this patch we can
utilize dual-role mode on dra7x boards. Please queue for -next. Thanks.
cheers,
-roger

USB1 port is micro-AB type and can function as peripheral
as well as host. Enable dual-role mode for USB1.
We don't want to use the OTG controller block on this
platform as it limits host mode to high-speed. Instead
we rely on extcon framework to give us ID events for
dual-role mode detection.
