AFAIK, U-Boot does not support runtime switching of USB port to
host from device and vice versa. This is the case for existing
driver like
DWC3/MUSB etc.

Ideally we would need a role switch driver that unbinds and rebinds

Hi Marek, Sherry,
we keep the cdns3 node for usb gadget driver, then add a usb host node
for
xhci-imx8 driver in *-uboot.dtsi. so here is no need to change the host driver
compatible.
But the compatible in gadget driver should be changed later.
We should try avoiding ABI breaks in DT.

Add the USB3 host driver for NXP imx8 platform, and the
cadence IP is in it. The USB3 host driver support DM
