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.
