+Common MDIO bus properties.
+
+These are generic properties that can apply to any MDIO bus.
+
+Optional properties:
+	- device-name - If present it is used to name the device and MDIO bus.
+			The name must be unique and must not contain spaces.
+
+A list of child nodes, one per device on the bus is expected.  These could be
+PHYs, switches or similar devices and child nodes should follow the specific
+binding for the device type.
+
+Example :
+This example shows the structure used for the external MDIO bus on NXP LS1028A
+RDB board.  Note that this MDIO device is an integrated PCI function and
+requires no compatible property for probing.
