Did you consider/reviewed patch series from Artur Petrosyan "[PATCH 
00/14] usb: dwc2: Fix and improve power saving modes" (submitted on 
April 12) which fixing partial power down and hibernation flows for both 
modes: host and device?
I suspect that this both patch series can be in conflict.

Thanks,
Minas
