Say Y here if your system has a Dual Role SuperSpeedUSB controller based on the DesignWare USB3 IP Core.
Say Y here if your system has DesignWare USB3 IP Core.if USB_DWC3
choice bool "DWC3 Mode Selection"
- default USB_DWC3_HOST if (USB && !USB_GADGET)
- default USB_DWC3_GADGET if (!USB && USB_GADGET)
What happens if I select both USB and USB_GADGET ?
Ideally we want to have dual role operation but that code seems to have been stripped off from the dwc3/core.c.
So till dual-role is added back it will work in HOST mode by default but user can still choose GADGET mode.
All right, not great, but let's go with this. Thanks
