Description:

		This file allows to read device descriptor of

		gadget driver which is currently bound to this

		controller. It is possible to read this file

		only if gadget driver is bound, otherwise error

		is returned.

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";

	};

* Broadcom SATA3 PHY for STB

* Broadcom SATA3 PHY

Required properties:

- compatible: should be one or more of

     "brcm,bcm7425-sata-phy"

     "brcm,bcm7445-sata-phy"

     "brcm,iproc-ns2-sata-phy"

     "brcm,phy-sata3"

- address-cells: should be 1

- size-cells: should be 0

- reg: register range for the PHY PCB interface

- reg-names: should be "phy"

- reg: register ranges for the PHY PCB interface

- reg-names: should be "phy" and "phy-ctrl"

     The "phy-ctrl" registers are only required for

     "brcm,iproc-ns2-sata-phy".

Sub-nodes:

  Each port's PHY should be represented as a sub-node.

Sub-nodes required properties:

- reg: the PHY number

- phy-cells: generic PHY binding; must be 0

Optional:

- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port

Sub-nodes optional properties:

- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port

     This property is not applicable for "brcm,iproc-ns2-sata-phy".

Example:

	sata-phy@f0458100 {

		compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3";

		reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>;

This binding describes a usb3.0 phy for mt65xx platforms of Medaitek SoC.

Required properties (controller (parent) node):

 - compatible	: should be "mediatek,mt8173-u3phy"

 - compatible	: should be one of

		  "mediatek,mt2701-u3phy"

		  "mediatek,mt8173-u3phy"

 - reg		: offset and length of register for phy, exclude port's

		  register.

 - clocks	: a list of phandle + clock-specifier pairs, one for each

- compatible: "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.

	      "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.

	      "renesas,usb-phy-r8a7794" if the device is a part of R8A7794 SoC.

	      "renesas,rcar-gen2-usb-phy" for a generic R-Car Gen2 compatible device.

	      When compatible with the generic version, nodes must list the

	      SoC-specific version corresponding to the platform first

	      followed by the generic version.

- reg: offset and length of the register block.

- #address-cells: number of address cells for the USB channel subnodes, must

		  be <1>.

Example (Lager board):

	usb-phy@e6590100 {

		compatible = "renesas,usb-phy-r8a7790";

		compatible = "renesas,usb-phy-r8a7790", "renesas,rcar-gen2-usb-phy";

		reg = <0 0xe6590100 0 0x100>;

		#address-cells = <1>;

		#size-cells = <0>;
