Series Skip phy initialization for DWC3 USB Controllers | expand

Commit Message

Sandeep Maheswaram April 21, 2022, 5 a.m. UTC 
Runtime suspend of phy drivers was failing from DWC3 driver as
runtime usage value is 2 because the phy is initialized from
DWC3 core and HCD core.
Some controllers like DWC3 and CDNS3 manage phy in their core drivers.
This property can be set to avoid phy initialization in HCD core.
