+*MDIO IO device
+
+The MDIO is a bus to which the PHY devices are connected. For each
+device that exists on this bus, a child node should be created.
+
+Required properties:
+ - compatible: Currently supported strings/devices are:
+ - "fsl,fman-xmdio" (Must be used for 10 Gb/s MDIO from
FMan v2.
+ Can be used for 1/10 Gb/s MDIO from FMan v3)
+ - "fsl,fman-memac-mdio" (Must be used for 1/10 Gb/s
MDIO from
+ FMan v3)
+ - reg
+
+ Example for FMan v2:
+ mdio@f1000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,fman-xmdio";
+ reg = <0xf1000 0x1000>;
+ };
+
+ Example for FMan v3:
+
+ mdio@f1000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,fman-memac-mdio", "fsl,fman-xmdio";
+ reg = <0xf1000 0x1000>;
+ }
