[Piyush]:
Will rephrase the commit message and send V2.

[Piyush]:
We have dedicated irq line for hibernation feature,  "hiber" irq line triggers hibernation interrupt.
DWC3 core supports the hibernation feature, we have a dedicated code which is yet to be upstreamed.
As the hibernation feature provided by dwc3-core, so this will be supported by other SOC/vendors.
