title: Marvell MV88E6xxx DSA switch family

description:
  The Marvell MV88E6xxx switch series has been produced and sold
  by Marvell since at least 2008. The switch has a few compatibles which
  just indicate the base address of the switch, then operating systems
  can investigate switch ID registers to find out which actual version
  of the switch it is dealing with.

    description: Marvell MV88E6xxx switches have an varying combination of
      internal and external MDIO buses, in some cases a combined bus that
      can be used both internally and externally. This node is for the
      primary bus, used internally and sometimes also externally.

      MDIO bus use this port to access external components on the MDIO bus.
