Various daughter cards can connect up via an RGMII connector or an RMII connector. The EDS board is not intended for stand-alone use and has no ethernet capabilities when no daughter board is connected. As such, this device tree is intended to be used with a DT overlay defining the add-on board. To better ensure consistency, some items are defined here as a form of documentation so that all add-on overlays will use the same terms.
