Right, in theory we have everything in place for gadget mode when this
patch-set lands and all someone needs to do is add a Kconfig option
for it. Note I do not plan to work on that ATM, only so much hours
in a day, etc. but I do invite others who are interested in this
to take a look at the gadget stuff and patches are welcome :)

This is the construct the other MUSB users use in their board code,
but yes either would work.
