1MVEBU A3700 UTMI PHY
2--------------------
3
4USB2 UTMI+ PHY controllers can be found on the following Marvell MVEBU SoCs:
5* Armada 3700
6
7On Armada 3700, there are two USB controllers, one is compatible with the USB2
8and USB3 specifications and supports OTG. The other one is USB2 compliant and
9only supports host mode. Both of these controllers come with a slightly
10different UTMI PHY.
11
12Required Properties:
13
14- compatible: Should be one of:
15	      * "marvell,a3700-utmi-host-phy" for the PHY connected to
16	        the USB2 host-only controller.
17	      * "marvell,a3700-utmi-otg-phy" for the PHY connected to
18	        the USB3 and USB2 OTG capable controller.
19- reg: PHY IP register range.
20- marvell,usb-misc-reg: handle on the "USB miscellaneous registers" shared
21			region covering registers related to both the host
22			controller and the PHY.
23- #phy-cells: Standard property (Documentation: phy-bindings.txt) Should be 0.

31		marvell,usb-misc-reg = <&usb2_syscon>;
32		#phy-cells = <0>;
33	};
