In this case when configuring the interface, there will be an attempt to connect to already attached PHY on the previously registered mdio bus: net eth1: PHY already attached net eth1: could not connect to phy smsc911x-0:01 IP-Config: Failed to open eth1 IP-Config: Device `eth1' not found Fix this by modifying match_first_device() to match first PHY device on 'davinci_mdio' bus.
