   12 description: |+
   13   This controller is mounted on development boards for Marvell's Link Street
   14   family of Ethernet switches. It allows you to configure the switch's registers
   15   using the standard MDIO interface.
   16 
   17   Since the device is connected over USB, there is no strict requirement of
   18   having a device tree representation of the device. But in order to use it with
   19   the mv88e6xxx driver, you need a device tree node in which to place the switch
   20   definition.
