+title: Marvell MDIO Ethernet Controller interface
+
+maintainers:
+  - Andrew Lunn <andrew@lunn.ch>
+
+description: |
+  The Ethernet controllers of the Marvel Kirkwood, Dove, Orion5x, MV78xx0,
+  Armada 370, Armada XP, Armada 7k and Armada 8k have an identical unit that
+  provides an interface with the MDIO bus. Additionally, Armada 7k and Armada
+  8k has a second unit which provides an interface with the xMDIO bus. This
+  driver handles these interfaces.
