Add support needed for the Renesas USB 3.0 controller (PD720201/PD720202). Without these patches a system with this USB controller will crash during boot.

Is this a regression, or something that has always happened? If a regression, any pointers to what commit caused this?

this really feels like a "new feature" addition to me, unless this used to work properly.

It is not a regression. It is a crash that occurs on new hardware that has this USB controller.

Without this patch series, hardware with this USB controller will fail to work. So in the choice between "regression" and "new feature" I would say "new feature".

Thanks,
