title: Marvell USB to MDIO Controller

|
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.
