Merge tag 'usb-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB/Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt changes for 5.18-rc1.

  Nothing major in here, just lots of little improvements and cleanups
  and new device support. Highlights are:

   - list iterator fixups for when we walk past the end of the list (a
     common problem that was cut/pasted in almost all USB gadget
     drivers)

   - xen USB driver "hardening" for malicious hosts

   - xhci driver updates and fixes for more hardware types

   - xhci debug cable fixes to make it actually work again

   - usb gadget audio driver improvements

   - usb gadget storage fixes to work with OS-X

   - lots of other small usb gadget fixes and updates

   - USB DWC3 driver improvements for more hardware types

   - Lots of other small USB driver improvements

   - DTS updates for some USB platforms

  All of these have been in linux-next for a while with no reported
  issues"

Description:

		The Enable/Disable sysfs interface for Embedded

		USB Debugger(EUD). This enables and disables the

		EUD based on a 1 or a 0 value. By enabling EUD,

		the user is able to activate the mini-usb hub of

		EUD for debug and trace capabilities.

   EHCI controller in host mode.

 - reg: physical base address of the controller and length of memory mapped

   region.

 - interrupts: interrupt number to the cpu.

 - clocks: from common clock binding: handle to usb clock.

 - clock-names: from common clock binding: Shall be "usbhost".

 - phys: from the *Generic PHY* bindings; array specifying phy(s) used

   by the root port.

 - phy-names: from the *Generic PHY* bindings; array of the names for

   each phy for the root ports, must be a subset of the following:

   "host", "hsic0", "hsic1".



Optional properties:

   needs to be pulled up for the bus to be powered.



Example:

				 with 'reg' property.

	   parent's address space

                 - samsung,exynos5433-dwusb3: "aclk", "susp_clk", "pipe_pclk",

                                              "phyclk",

                 - samsung,exynos7-dwusb3: "usbdrd30", "usbdrd30_susp_clk",

                                           "usbdrd30_axius_clk"

 - vdd10-supply: 1.0V powr supply

 - vdd33-supply: 3.0V/3.3V power supply



Sub-nodes:

The dwc3 core should be added as subnode to Exynos dwc3 glue.

- dwc3 :

   The binding details of dwc3 can be found in:

   Documentation/devicetree/bindings/usb/snps,dwc3.yaml



Example:

	usb@12000000 {

		compatible = "samsung,exynos5250-dwusb3";

		clocks = <&clock 286>;

		clock-names = "usbdrd30";

		#address-cells = <1>;

		#size-cells = <1>;

		ranges;

		vdd10-supply = <&ldo11_reg>;

		vdd33-supply = <&ldo9_reg>;



		dwc3 {

			compatible = "synopsys,dwc3";

			reg = <0x12000000 0x10000>;

			interrupts = <0 72 0>;

			usb-phy = <&usb2_phy &usb3_phy>;
