Hi Geert,

This series describes the two Marvell 88Q2110 PHYs connected to AVB1 and 
AVB2 found on the Gray Hawk Single board.

Patch 1/2 is a small cleanup patch preparing for the addition of the 
88Q2110 PHYs which require the use of an MDIO node as the bus needs to 
be reset before the PHY can be probed.

While not strictly needed I also rework AVB0 to have a MDIO node for 
consistency. Please note I do not move where the PHY is reset so the 
controversy debated in [1] is not in play here. If that ever gets 
positively resolved this will need to be updated as well.

While patch 2/2 enables AVB1 and AVB2 and describe the two 88Q2110 PHYs.

With this series applied all three AVB instances probe and can attach to 
their respective PHY.
