Merge tag 'usb-6.13-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 6.13-rc1.

  Overall, a pretty slow development cycle, the majority of the work
  going into the debugfs interface for the thunderbolt (i.e. USB4) code,
  to help with debugging the myrad ways that hardware vendors get their
  interfaces messed up. Other than that, here's the highlights:

   - thunderbolt changes and additions to debugfs interfaces

   - lots of device tree updates for new and old hardware

   - UVC configfs gadget updates and new apis for features

   - xhci driver updates and fixes

   - dwc3 driver updates and fixes

   - typec driver updates and fixes

   - lots of other small updates and fixes, full details in the shortlog

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