Merge tag 'usb-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big USB and thunderbolt pull request for 5.11-rc1.

  Nothing major in here, just the grind of constant development to
  support new hardware and fix old issues:

   - thunderbolt updates for new USB4 hardware

   - cdns3 major driver updates

   - lots of typec updates and additions as more hardware is available

   - usb serial driver updates and fixes

   - other tiny USB driver updates

  All have been in linux-next with no reported issues"
