Hisilicon Kirin970 usb PHY

-----------------------



Required properties:

- compatible: should be "hisilicon,hi3670-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,sctrl-syscon: phandle of syscon used to control phy.

- hisilicon,usb31-misc-syscon: phandle of syscon used to control phy.

- eye-diagram-param: parameter set for phy

- usb3-phy-tx-vboost-lvl: parameter set for phy

Refer to phy/phy-bindings.txt for the generic PHY binding properties



Example:

	usb_phy: usbphy {

		compatible = "hisilicon,hi3670-usb-phy";

		#phy-cells = <0>;

		hisilicon,pericrg-syscon = <&crg_ctrl>;

		hisilicon,pctrl-syscon = <&pctrl>;

		hisilicon,sctrl-syscon = <&sctrl>;

		hisilicon,usb31-misc-syscon = <&usb31_misc>;

		eye-diagram-param = <0xFDFEE4>;

		usb3-phy-tx-vboost-lvl = <0x5>;

	};
