Currently (in the vendor tree) one of the phys lives in
drivers/usb/phy and the other in drivers/phy.
I believe that is because one is only a usb phy and the other is a
multi function phy which can drive PCI-E or USB3.
right, but for mainline, we can have both PHYs in drivers/phy only.
Ah ok, I didn't know that, so thanks for that info.

So to make that work, when dwc3/core.c gets the PHYS in
dwc3_core_get_phy() we need to use the different bindings.

I think we are the only platform using "one of each", but luckily
dwc3_core_get_phy() has been written generically enough that it "just
works" :-).
true, but I want to drop support for the legacy drivers/usb/phy layer
from dwc3. I'll try to move all PHYs to drivers/phy for v3.18.
Ok, so for the next re-spin I will change this to just use the generic
phy binding for both usb2 & usb3 phys.

In parallel I will also migrate over the drivers/usb/phy driver to be
just a generic phy before I attempt to upstream it.
Thank you for understanding :-)
