offload, phandle of the TAH device node.
- tah-channel : 1 cell, optional. If appropriate, channel used on the
TAH engine.
- fixed-link : Fixed-link subnode describing a link to a non-MDIO

- mdio subnode : When the EMAC has a phy connected to its local
mdio, which us supported by the kernel's network
PHY library in drivers/net/phy, there must be device
tree subnode with the following required properties:
