Merge tag 'usb-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt driver updates from Greg KH:
 "Here is the big set of USB and Thunderbolt driver updates for 6.5-rc1.

  Included in here are:

   - Lots of USB4/Thunderbolt additions and updates for new hardware
     types and fixes as people are starting to get access to the
     hardware in the wild

   - new gadget controller driver, cdns2, added

   - new typec drivers added

   - xhci driver updates

   - typec driver updates

   - usbip driver fixes

   - usb-serial driver updates and fixes

   - lots of smaller USB driver updates

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