v1:
* Fix some format error as suggested by Rob.
v2:
* Change hi3660 usb PHY to hi3660 USB PHY
v3:
* Make device node a subnode of usb3_otg_bc register.

+Hisilicon hi3660 USB PHY
+-----------------------
+
+Required properties:
+- compatible: should be "hisilicon,hi3660-usb-phy"
+- #phy-cells: must be 0
+- hisilicon,pericrg-syscon: phandle of syscon used to control phy.
+- hisilicon,pctrl-syscon: phandle of syscon used to control phy.
+- hisilicon,usb3-otg-bc-syscon: phandle of syscon used to control phy.
+- hisilicon,eye-diagram-param: parameter set for phy
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+This is a subnode of usb3_otg_bc register node.
+
+Example:
+	usb3_otg_bc: usb3_otg_bc@ff200000 {
+		compatible = "syscon", "simple-mfd";
+		reg = <0x0 0xff200000 0x0 0x1000>;
+
+		usb-phy {
+			compatible = "hisilicon,hi3660-usb-phy";
+			#phy-cells = <0>;
+			hisilicon,pericrg-syscon = <&crg_ctrl>;
+			hisilicon,pctrl-syscon = <&pctrl>;
+			hisilicon,usb3-otg-bc-syscon = <&usb3_otg_bc>;
+			hisilicon,eye-diagram-param = <0x22466e4>;
+		};
