The second reference in the example is missing the last cell,
as you have #phy-cells = <2>.

Further, the binding for "generic-ehci" requires the name to be "usb",
not "usbp0". You should probably update that binding if you can have
multiple references to mention that.

Can you make both names "usb"? If not, we should document a common
naming scheme that the driver can use.
