   13 description:
   14   On Armada 3700, there are two USB controllers, one is compatible with
   15   the USB2 and USB3 specifications and supports OTG. The other one is USB2
   16   compliant and only supports host mode. Both of these controllers come with
   17   a slightly different UTMI PHY.
