Daniel,

These messages are typical of having the wrong GPIO pins in the mdio
node or the wrong MDIO address (reg property) in the ethernet-phy node.

The driver definitely tries to talk to the PHY using the GPIO pins
and address specified and if it doesn't respond, it won't attach.

The mdio driver works without interrupts.  I have no interrupt-parent
or interrupts properties on my ethernet-phy node.
