Merge tag 'usb-7.0-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 driver updates for
  7.0-rc1. Overall more lines were removed than added, thanks to
  dropping the obsolete isp1362 USB host controller driver, always a
  nice change.

  Other than that, nothing major happening here, highlights are:

   - lots of dwc3 driver updates and new hardware support added

   - usb gadget function driver updates

   - usb phy driver updates

   - typec driver updates and additions

   - USB rust binding updates for syntax and formatting changes

   - more usb serial device ids added

   - other smaller USB core and driver updates and additions

  All of these have been in linux-next for a long time, with no reported
  problems"
