+APM X-Gene SoC MDIO node
+
+MDIO node is defined to describe on-chip MDIO controller.
+
+Required properties:
+ - compatible: Must be "apm,xgene-mdio-rgmii" or "apm,xgene-mdio-xfi"
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+ - reg: Address and length of the register set
+ - clocks: Reference to the clock entry
+
+For the phys on the mdio bus, there must be a node with the following fields:
+ - compatible: PHY identifier. Please refer ./phy.txt for the format.
+ - reg: The ID number for the phy.
+
+Example:
+
+ mdio: mdio@...20000 {
+ compatible = "apm,xgene-mdio-rgmii";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x0 0x17020000 0x0 0xd100>;
+ clocks = <&menetclk 0>;
+ };
+
+ /* Board-specific peripheral configurations */
+ &mdio {
+ menetphy: phy@3 {
+ reg = <0x3>;
+ };
+ sgenet0phy: phy@4 {
+ reg = <0x4>;
+ };
+ sgenet1phy: phy@5 {
+ reg = <0x5>;
+ };
+ };
