Thanks for your suggestions.
So if I want to use the cdns3 usb node as both usb gadget device and usb host
device,
do you mean that I should make the cdns3 usb node as a usb wrapper device, and
create two subnodes in it.
Then when binding the wrapper node, it will hard-coded the two subnodes to
different driver(gadge/host driver)
according to the dr_mode property in nodes.
