+Juniper SAM FPGA MFD MDIO bus properties.
+
+Required properties:
+- compatible : "jnx,mdio-sam"
+- reg : The start offset of the MDIO bus range
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+
+Required properties for child nodes:
+- #address-cells = <1>;
+- #size-cells = <0>;
+- reg : The MDIO bus offset within the MDIO range.

+
+Example :
+

+		#size-cells = <0>;
