| Several clocks are used, depending on the variant. Typical ones are:: |

| 60MHz for HS operation. |
| - iface:: System bus AXI clock. |
| - sleep:: Sleep clock, used for wakeup when USB3 core goes into low |
| power mode (U3). |
| - mock_utmi:: Mock utmi clock needed for ITP/SOF generation in host |
| mode. Its frequency should be 19.2MHz. |
