Merge tag 'usb-6.16-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 6.16-rc1.
  Included in here are the following:

   - USB offload support for audio devices.

     I think this takes the record for the most number of patch series
     (30+) over the longest period of time (2+ years) to get merged
     properly.

     Many props go to Wesley Cheng for seeing this effort through, they
     took a major out-of-tree hacked-up-monstrosity that was created by
     multiple vendors for their specific devices, got it all merged into
     a semi-coherent set of changes, and got all of the different major
     subsystems to agree on how this should be implemented both with
     changes to their code as well as userspace apis, AND wrangled the
     hardware companies into agreeing to go forward with this, despite
     making them all redo work they had already done in their private
     device trees.

     This feature offers major power savings on embedded devices where a
     USB audio stream can continue to flow while the rest of the system
     is sleeping, something that devices running on battery power really
     care about. There are still some more small tweaks left to be done
     here, and those patches are still out for review and arguing among
     the different hardware companies, but this is a major step forward
     and a great example of how to do upstream development well.

   - small number of thunderbolt fixes and updates, things seem to be
     slowing down here (famous last words...)

   - xhci refactors and reworking to try to handle some rough corner
     cases in some hardware implementations where things don't always
     work properly

   - typec driver updates

   - USB3 power management reworking and updates

   - Removal of some old and orphaned UDC gadget drivers that had not
     been used in a very long time, dropping over 11 thousand lines from
     the tree, always a nice thing, making up for the 12k lines added
     for the USB offload feature.

   - lots of little updates and fixes in different drivers

  All of these have been in linux-next for over 2 weeks, the USB offload
  logic has been in there for 8 weeks now, with no reported issues"
