+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
+
+Example:
+	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>;
+	};
