+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.
+- eye-diagram-param: parameter set for phy
+Refer to phy/phy-bindings.txt for the generic PHY binding properties
+
+Example:
+	usb_phy: usbphy {
+		compatible = "hisilicon,hi3660-usb-phy";
+		#phy-cells = <0>;
+		hisilicon,pericrg-syscon = <&crg_ctrl>;

+HiSilicon DWC3 USB SoC controller
+
+This file documents the parameters for the dwc3-hisi driver.
+
+Required properties:
+- compatible:	should be "hisilicon,hi3660-dwc3" or "hisilicon,kirin970-dwc3"
+- clocks:	A list of phandle + clock-specifier pairs for the
+		clocks listed in clock-names
+- clock-names:	Specify clock names
+- resets:	list of phandle and reset specifier pairs.
+
+Sub-nodes:
+The dwc3 core should be added as subnode to HiSilicon DWC3 as shown in the
+example below. The DT binding details of dwc3 can be found in:
+Documentation/devicetree/bindings/usb/dwc3.txt
