USB gadget is not working fully as expected on RK3328, it uses a board_usb_init() function to initialize the DWC2 OTG port. The board_usb_init() function does not intgrate with the generic phy framework and as a result the USB phy is not properly configured before or after USB gadget use. Having both USB_DWC2 and DWC2_OTG enabled for the same board is also causing some issues. Trying to use rockusb or ums command after usb stop result in a freeze due to usb stop is putting the phy in a suspended state. => usb start => usb stop => ums 0 mmc 0 --> freeze due to usb phy is suspended <-- Fix this by only using one of USB_DWC2 (host) or DWC2_OTG (peripheral) depending on the most likely usage of the otg port and by migrating to use DM_USB_GADGET instead of a board_usb_init() function. The nanopi-r2 and orangepi-r1-plus variants share OTG and power using a Type-C connector, mark these boards dr_mode as peripheral, the most likely usage is for recove...
