In the arch/arm/boot/dts/at91-sama5d3_ksz9477_evb.dts file, they
haven't specified the phy-handle. If I use that dts file with this
patch, during the mdio_register I get the error *no mdio bus node* and
the ksz probe fails. If I update the dts file with phy-handle  and mdio
node, the mdio_register is successfull and interrupt handling works
fine. Do I need to add any checks before mdio_register or updating the
dts file is enough?
