The switch has a few compatibles which15 just indicate the base address of the switch, then operating systems16 can investigate switch ID registers to find out which actual version17 of the switch it is dealing with.18 19properties:20 compatible:21 oneOf:22 - enum:23 - marvell,mv88e608524 - marvell,mv88e619025 - marvell,mv88e625026 description: |27 marvell,mv88e6085: This switch uses base address 0x10.28 This switch and its siblings will be autodetected from29 ID registers found in the switch, so only "marvell,mv88e6085" should be30 specified.
