description: |
Several clocks are used, depending on the variant. Typical ones are::
- cfg_noc:: System Config NOC clock.
- core:: Master/Core clock, has to be >= 125 MHz for SS operation and >=
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.
