I think we need to understand this better. Why does it fail?

I gave a test on an imx6q-sabresd and the Ethernet PHY (AR8031) could
be properly detected using reset-{assert-us,deassert-us,gpios}
properties inside the mdio node.

Is this a Micrel KSZ8081 specific issue?

Please report this issue to the Ethernet PHY folks.
