		Description:
		This file allows to read device descriptor of
		gadget driver which is currently bound to this

		Date: April 2016
		KernelVersion: 4.6
		Contact: Krzysztof Opasiak <k.opasiak@samsung.com>
		Description:
		This file allows to export usb device to
		connection peer. It is done by writing to this
		file socket fd (as a string for example "8")
		associated with a connection to remote peer who
		would like to use this device. It is possible to
		close the connection by writing -1 instead of
		socked fd.

		Driver for Broadcom Northstar USB 2.0 PHY

		Required properties:
		- compatible: brcm,ns-usb2-phy
		- reg: iomem address range of DMU (Device Management Unit)
		- reg-names: "dmu", the only needed & supported reg right now
		- clocks: USB PHY reference clock
		- clock-names: "phy-ref-clk", the only needed & supported clock right now

		To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
		requires passing phandle to the USB PHY reference clock.

		Example:
		usb2-phy {
		compatible = "brcm,ns-usb2-phy";
		reg = <0x1800c000 0x1000>;
		reg-names = "dmu";
		#phy-cells = <0>;
		clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>;
		clock-names = "phy-ref-clk";
		};
