+Required bus properties:
+- reg: MDIO Bus number for the MDIO interface
+- #address-cells: must be 1
+- #size-cells: must be 0
+
+Required PHY properties:
+- compatible: should be "brcm,ns2-pcie-phy"
+- reg: MDIO Phy ID for the MDIO interface
+- #phy-cells: must be 0
+
+This is a child bus node of "brcm,mdio-mux-iproc" node.
+
+Example:
+
+mdio@0 {
+       reg = <0x0>;
+       #address-cells = <1>;
+       #size-cells = <0>;
+
+       pci_phy0: pci-phy@0 {
+               compatible = "brcm,ns2-pcie-phy";
+               reg = <0x0>;
+               #phy-cells = <0>;
+       };
+};
