Pull USB / Thunderbolt updates from Greg KH:
 "Here is the large set of USB and Thunderbolt changes for 6.4-rc1.

  The "biggest" thing in here is the removal of two obsolete drivers,
  u132-hcd and ftdi-elan, making this a net-removal of code overall.

  Other than the driver removals, included in here are:

   - Thunderbolt updates for new hardware and features

   - xhci driver updates and fixes

   - dwc3 driver updates and fixes

   - gadget core and driver updates and features added

   - mtu3 driver updates

   - dwc2 driver fixes and updates

   - usb-serial driver updates

   - typec driver updates and fixes

   - platform remove callback changes

   - dts updates and conversions

   - other small changes

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