Hi,
Sorry for the late feedback but I didn't notice this until I looked at
the pull request from Jason.
Please go back and revisit these bindings. I'll merge in the current
version but they need to be fixed up.
Also, always cc devicetree-discuss and the DT maintainers on new bindings.

This isn't an appropriate binding for phy. I know, it maps straight
over from the platform data, but it doesn't focus on what the actual
hardware is.
A couple of options. What probably makes most sense depending on how
other phy bindings are moving ahead is to add a phy node under the
ehci controller for the "orion5x" case, and have an appropriate
compatible value there. No node means the same as "NA" in the above
binding. Alternatively, have a phy phandle that points to the phy
device if it sits on an i2c bus, etc.
