To extend what Andrew stated above, Documentation/devicetree/bindings/net/dsa/marvell.txt
(as of 22936c3e6e8c) says which of the two strings you should use for
each model.

The "marvell,mv88e6085" and "marvell,mv88e6190" compatible strings are
best thought of as the "where is the identification register" setting;
from that point the driver can figure out everything else.
