Merge tag 'usb-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

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

  It's been an active set of development in these subsystems for the
  past few months:

   - loads of typec features added for new hardware

   - xhci features and bugfixes

   - dwc3 features added for more hardware support

   - dwc2 fixes and new hardware support

   - cdns3 driver updates for more hardware support

   - gadget driver cleanups and minor fixes

   - usb-serial fixes, new driver, and more devices supported

   - thunderbolt feature additions for new hardware

   - lots of other tiny fixups and additions

  The chrome driver changes are in here as well, as they depended on
  some of the typec changes, and the maintainer acked them.

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