nice :-) Clearly there's a shortcoming in the current PHY framework to discover
PHY's behind a pci. Thanks for attempting to solve it.

But I think it needs a few modification like the ULPI device should be created
by the glue (dwc3-pci?) and phy create should be done in phy driver. We should
think of a better way for the controller to find the PHY (lets try and not use
PHY CONSUMER or device name).

Thanks
Kishon
