Hello all,
I'm working on a new USB device controller driver for U-Boot.
And I need some advice how to properly implement it.

Could you please describe what is gadget.ep0?
- Why ep0 defined separetly (not included in end points list)?
- Why other end-points has "in" and "out" `struct usb_ep` descriptor, but not ep0?
