Marvell seems to distinguish the USB PHY type by technology node, e.g. 28nm like the one above. For the most used Marvell SoCs, i.e. Kirkwood, Dove, and Armada 370/XP, they all use a different technology node and we could either use the SoC name or the technology node as compatible. Anyway, if you are introducing new PHY drivers with _that_ generic names, it will either clash with every other Marvell USB PHYs - or we'll have to add the PHY code into the drivers above.
