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.
