+Hisilicon Fast Ethernet MDIO Controller interface
+
+Required properties:
+- compatible: should be "hisilicon,hisi-femac-mdio".
+- reg: address and length of the register set for the device.
+- clocks: A phandle to the reference clock for this device.
+
+- PHY subnode: inherits from phy binding [1]
+[1] Documentation/devicetree/bindings/net/phy.txt
+
+Example:
+mdio: mdio@10091100 {
+ compatible = "hisilicon,hisi-femac-mdio";
+ reg = <0x10091100 0x10>;
+ clocks = <&crg HI3516CV300_MDIO_CLK>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ phy0: phy@1 {
+ reg = <1>;
+ };
+};
