Quoting ethernet.txt:

- phy: the same as "phy-handle" property, not recommended for new bindings.

- phy-handle: phandle, specifies a reference to a node representing a PHY
  device; this property is described in the Devicetree Specification and so
  preferred;

Can this be expressed in Yaml? Accept phy, but give a warning. Accept
phy-handle without a warning? Enforce that one or the other is
present?

Thanks
