+Broadcom iProc MDC/MDIO bus interface
+
+The iProc MDC/MDIO bus interface is found on various iProc based SoCs and is
+used to communicate with various types of Serdes/PHYs including Ethernet,
+PCIe, USB, and etc.
+
+Required properties:
+- compatible: Must be "brcm,iproc-mdio"
+- reg: base address and length of the MDC/MDIO interface
+- address-cells: must be 1
+- size-cells: must be 1
+- ranges: leave it empty
+
+Example:
+ mdio_bus: mdio_bus@18002000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "brcm,iproc-mdio";
+ ranges;
+ reg = <0x18002000 0x8>;
+ };
