We've been using the patches from Ian Molton for the mv643xx driver

Where the MDIO bus is explicit, the PHY, its address and parameters
are explicit - the PHY has an of_node pointer - and phy-handle is used
to connect them.

I'm not sure having the MDIO bus as a distinct top level item is
great, considering how the registers overlap.. It might be better
to put it under the egiga0 block? But that is a minor nit :)

Thanks for your comment. I'll see what I can come up with to make the
phy a separate DT entity.

Thanks!
