The same code used by the ENETC ports (eth controllers) to manage MDIO via local registers applies and is reused. Bindings are provided for the new MDIO node, similarly to ENETC port nodes bindings. Last patch enables the ENETC port 1 and its RGMII PHY on the LS1028A QDS board, where the MDIO muxing configuration relies on the MDIO support provided in the first patch.
