The USB client requires the usb30_prim gdsc to be kept active for
certain use cases, thus add the GENPD_FLAG_ACTIVE_WAKEUP flag.
Can you please describe more of what this is for? Once sentence doesn't
tell me much at all. I guess that sometimes we want to wakeup from USB
and so the usb gdsc should be marked as "maybe keep on for wakeups" with
the GENPD_FLAG_ACTIVE_WAKEUP flag if the USB controller is wakeup
enabled?

Add a Fixes: tag too? And I assume we need to do this for all USB gdscs
on various SoCs and maybe other GDSCs like PCIe. Any plans to fix those
GDSCs?

Any update here?

I moved this change to usb driver code dwc3-qcom.c in v2 of this series https://patchwork.kernel.org/cover/11652281/
