The SAMA5D3-EDS board is an Ethernet Development Platform allowing for evaluating many Microchip ethernet switch and PHY products. 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.
