Adding bindings for usb-skip-phy-init property.
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.
You already know if you have a DWC3 and CDNS3 controller, so you don't
need more data in DT.
We don't have a device tree node for xhci platform device and create xhci
platform device from dwc3/host.c
So we want to pass this property to check in xhci-plat.c and skip phy
initialization.
Would not the below condition from your other patch [1] work here too?
if (of_device_is_compatible(dev->parent->of_node, "snps,dwc3"))

Yes. This condition is working. Will send the new version with this change.
