Merge tag 'usb-5.13-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 updates for
5.13-rc1.
Lots of little things in here, with loads of tiny fixes and cleanups
over these drivers, as well as these "larger" changes:
- thunderbolt updates and new features added
- xhci driver updates and split out of a mediatek-specific xhci
driver from the main xhci module to make it easier to work with
(something that I have been wanting for a while).
- loads of typec feature additions and updates
- dwc2 driver updates
- dwc3 driver updates
- gadget driver fixes and minor updates
- loads of usb-serial cleanups and fixes and updates
- usbip documentation updates and fixes
- lots of other tiny USB driver updates
All of these have been in linux-next for a while with no reported
issues"
