* Amlogic Meson GXL and GXM USB3 PHY and OTG detection binding

Required properties:
- compatible:	Should be "amlogic,meson-gxl-usb3-phy"
- #phys-cells:	must be 0 (see phy-bindings.txt in this directory)
- reg:		The base address and length of the registers
- interrupts:	the interrupt specifier for the OTG detection
- clocks:	phandles to the clocks for
		- the USB3 PHY
		- and peripheral mode/OTG detection
- clock-names:	must contain "phy" and "peripheral"
- resets:	phandle to the reset lines for:
		- the USB3 PHY and
		- peripheral mode/OTG detection
- reset-names:	must contain "phy" and "peripheral"

Optional properties:
- phy-supply:	see phy-bindings.txt in this directory


Example:
	usb3_phy_v2: usb3phy@ffe09080 {
			compatible = "amlogic,amlogic-new-usb3-v2";

			#phy-cells = <0>;
			reg = <0x0 0xffe09080 0x0 0x20
					0x0 0xffd01008 0x0 0x100>;
			phy-reg = <0xff646000>;
			phy-reg-size = <0x2000>;
			usb2-phy-reg = <0xffe09000>;
			usb2-phy-reg-size = <0x80>;
			interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
			pwr-ctl = <1>;
			u3-ctrl-sleep-shift = <18>;
			u3-hhi-mem-pd-shift = <26>;
			u3-hhi-mem-pd-mask = <0xf>;
