^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2) --------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) USB2 UTMI+ PHY controllers can be found on the following Marvell MVEBU SoCs:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) * Armada 3700
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) On Armada 3700, there are two USB controllers, one is compatible with the USB2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) and USB3 specifications and supports OTG. The other one is USB2 compliant and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) only supports host mode. Both of these controllers come with a slightly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) different UTMI PHY.
