+title: Marvell USB to MDIO Controller
+
+maintainers:
+ - Tobias Waldekranz <tobias@waldekranz.com>
+
+description: |+
+ This controller is mounted on development boards for Marvell's Link Street
+ family of Ethernet switches. It allows you to configure the switch's registers
+ using the standard MDIO interface.
+
+ Since the device is connected over USB, there is no strict requirement of
+ having a device tree representation of the device. But in order to use it with
+ the mv88e6xxx driver, you need a device tree node in which to place the switch
+ definition.
