USB device controller (UDC) driver API
The USB device controller driver API is described in
include/zephyr/drivers/usb/udc.h and referred to
as the UDC driver API.
UDC driver API is experimental and is subject to change without notice. It is a replacement for USB device controller driver API. If you wish to port an existing driver to UDC driver API, or add a new driver, please use drivers/usb/udc/udc_skeleton.c as a starting point.
