+Properties for an MDIO bus mutiplexer found in Broadcom iProc based SoCs.
+
+This MDIO bus multiplexer defines buses that could be internal as well as
+external to SoCs and could accept MDIO transaction compatible to C-22 or
+C-45 Clause. When child bus is selected, one needs to select these two
+properties as well to generate desired MDIO trascation on appropriate bus.
+
+Required properties in addition to the generic multiplexer properties:
+
+MDIO multiplexer node:
+- compatible: brcm,mdio-mux-iproc.
+
+Every non-ethernet PHY requires a compatible so that it could be probed based
+on this compatible string.
+
+Additional information regarding generic multiplexer properties can be found
+at- Documentation/devicetree/bindings/net/mdio-mux.txt
+
+
+for example:
+   mdio_mux_iproc: mdio-mux@6602023c {
+   compatible = "brcm,mdio-mux-iproc";
+   reg = <0x6602023c 0x14>;
+   #address-cells = <1>;
+   #size-cells = <0>;
+
+   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>;
+   };
+   };
+
+   mdio@7 {
+   reg = <0x7>;
+   #address-cells = <1>;
+   #size-cells = <0>;
+
+   pci_phy1: pci-phy@0 {
+   compatible = "brcm,ns2-pcie-phy";
+   reg = <0x0>;
+   #phy-cells = <0>;
+   };
+   };
+   mdio@10 {
+   reg = <0x10>;
+   #address-cells = <1>;
+   #size-cells = <0>;
+
+   gphy0: eth-phy@10 {
+   reg = <0x10>;
+   };
+   };
+   };
