Hi Martin

I know Linus wants to replace all users of old GPIO numbers with gpio
descriptors. So your patches have value, even if you don't need them.

One other things to watch out for. We have generic code at two
levels. Either the GPIO is per PHY, and the properties should be in
the PHY node, or the reset is for all PHYs of an MDIO bus, and then
the properties should be in the MDIO node.
