The OTG block is based on ChipIdea and works with "chipidea,usb2"
compatible driver as is just by adding the PHY driver. Yay!

[Adding some MVEBU guys]

Rob,

I had a look at the USB PHYs of some of the other Marvell SoCs a while
ago for the barebox bootloader [1]. 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.
