+Microsemi MII Management Controller (MIIM) / MDIO
+=================================================
+
+Properties:
+- compatible: must be "mscc,ocelot-miim"
+- reg: The base address of the MDIO bus controller register bank. Optionally, a
+ second register bank can be defined if there is an associated reset register
+ for internal PHYs
+- #address-cells: Must be <1>.
+- #size-cells: Must be <0>. MDIO addresses have no size component.
+- interrupts: interrupt specifier (refer to the interrupt binding)
+
+Typically an MDIO bus might have several children.
+
+Example:
+ mdio@107009c {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "mscc,ocelot-miim";
+ reg = <0x107009c 0x36>, <0x10700f0 0x8>;
+ interrupts = <14>;
+
+ phy0: ethernet-phy@0 {
+ reg = <0>;
+ };
+ };
