You misunderstood me about the compatible property.  You don't need a
compatible prop in the mdio node because it is *alwasy* a child of the
emaclite node, and the emaclite driver knows to go looking for it (ie.
it is a part of the device).

What I want to see is a compatible value in the phy@7 node for the
make & model of the phy.

Otherwise, looks good to me.  Fix the mutex timeout problem and then
you can add my acked-by line to the patch.

Cheers,
g.
