| Say Y or M here if your system has an on-chip Cadence USB |
| dual-role controller. This covers both USBSS (USB 3.0) and |
| USBSSP (SuperSpeed Plus) IP; the driver detects the variant at |
| runtime. |
| |
| The core driver (core, DRD, generic platform binding for the |
| "cdns,usb3" device tree compatible, optional host and gadget) |
| builds as one module named cdns.ko when built as a loadable |
| module. |
| |
| It supports: dual-role switch, Host-only, and Peripheral-only. |

| |
| USBSS gadget supports FF, HS and SS mode (not LS or SSP). |
| USBSSP gadget supports FF, HS, SS and SSP mode (not LS). |
