[PATCH v3 4/9] usb: chipidea: tegra: Rename UDC to USB

Dmitry Osipenko
2020-12-18T12:12:34Z

Rename all occurrences in the code from "udc" to "usb" and change the
Kconfig entry in order to show that this driver supports USB modes other
than device-only mode. The follow up patch will add host-mode support and
it will be cleaner to perform the renaming separately, i.e. in this patch.
