Oops sorry, in fact that's also mainline. Interesting to learn it ;-)
Quickly looking at the code, it seems that usbtty is not using the same
API as the other gadgets in drivers/usb/gadget : it doesn't call
usb_gadget_register_driver and instead call the udc functions directly.
So indeed in the present state, this driver can't work on an i.MX6.
Eric
