Platforms which do not select MISC will lose DWC3 now, did you verify that no platform is affected ?
This is what it is going to happen when MISC is not enabled.

It means if any platform is not enabling MISC then they have bigger problem then just missing DWC3.
Anyway only ZynqMP board enables it and all of them have MISC enabled.

I wanted to apply this, but it doesn't apply to u-boot-usb/master .
Good thing on this is that "dwc3-generic: Handle the PHYs, the clocks and the reset lines" has done this change already. (Before I sent this I was checking Jean's patches for DWC3 but didn't find this change :-()
Anyway please ignore this patch.
Thanks, Michal
