This adds support for isochronous endpoints to gadget zero and the usbtest module. We have used something similar to this for testing our super speed device and host controllers, but it would be easier (and require less support) to have this in the mainline kernel. Does this look like the right approach? I know the zero gadget is supposed to be very simple, and this complicates it a bit. But making a separate gadget for this would require duplicating quite a bit of code, I think. At least I don't see a clean way to make the isoc support modular and optional. I have tested this with the Synopsys device and host, at high speed and super speed. It still needs testing with a UDC that doesn't support super speed or isoc, to make sure the simple case is not broken. Comments?
