-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,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,eye-diagram-param = <0x22466e4>;
