I found my udc in v4.6. I played around with the kernel config for a
while and found the option that enables it. I think I changed dwc3 from
'dual role' (otg I guess) to 'peripherial' and got it's UDC and got a
few gadgets going.
We are using xilinx ZynqMP SOC and the BSP they support for v16.4 is
4.6. v17.1 is out and it is linux kernel 4.9. I did try linux-next,
but reverted back to 4.6, when I got the UDC driver working.
Much thanks, I will definitely follow where this is going on linux-usb.

We are moving platforms from musb on 2.6.37 to dwc3 on 4.6. Whew, a lot
why v4.6? why not v4.10 fresh out of the oven? Who's making you stuck on
older kernels? Seems like you should ask for support from that company.
has changed since we were stuck on the old kernel.
It looks like libusbgx and udc is the current method for a complex
video/web gadget ( uvc and a couple of uac gadgets).
Is UDC missing from 4.6? If so then what kernel should support it?
dwc3 has been around for a long time :-)
