Sören's marvell,* entries do not seem documented, therefore I used the
documented "ethernet-phy-idAAAA.BBBB" based syntax. The documented
example specifically uses -c22, too.
Either it's okay to prepend unrecognized model strings, then you should
update zynq-parallella.dts as well (I put the model in a comment there)
or use the official strings like I used and keep the readable models as
comments. Documenting all those "marvell,88e1116r", "marvell,88e1518",
"marvell,88e1318" PHY bindings and possibly prepending them to the ID
based strings would be another option, of course.

Andreas
