Felipe writes: USB: more changes for v5.3 merge window Turns out a few more important changes came about. We have the new Cadence DRD Driver being added here and that's the biggest, most important part. Together with that we have suport for new imx7ulp phy. Support for TigerLake Devices on dwc3. Also a couple important fixes which weren't completed in time for the -rc cycle.
