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.
