As far as I know, this is a "Synopsys USB 2.0 High Speed Altantic
Controller". There are different drivers in mainline for this core:

- ci13xxx_udc
- fsl_usb_core
- langwell_udc

I think there even was a fourth, but I can't remember which one.

All with a different level of abstraction and features.
