Hi Jeremy
You need to be careful here, when you say "use DT". With a c45 PHY
of_mdiobus_register_phy() calls get_phy_device() to see if the device
exists on the bus. So your changes to get_phy_device() etc, needs to
continue to find devices it used to find, even if they are not fully
complient to 802.3.
