+* Marvell MDIO Ethernet Controller interface
+
+The Ethernet controllers of the Marvel Armada 3700 and Armada 7k/8k
+have an identical unit that provides an interface with the MDIO bus.
+This driver handles this MDIO interface.
+
+Mandatory properties:
+SoC specific:
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+ - compatible: Should be "marvell,orion-mdio" (for SMI)
+ "marvell,xmdio" (for XSMI)
+ - reg: Base address and size SMI/XMSI bus.
+
+Please refer to "mdio.txt" for generic MDIO bus bindings.

+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.
