Merge tag 'usb-6.0-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 Thunderbolt and USB changes for 6.0-rc1.
Lots of little things here, nothing major, just constant development
on some new hardware support and cleanups of older drivers. Highlights
are:
- lots of typec changes and improvements for new hardware
- new gadget controller driver
- thunderbolt support for new hardware
- the normal set of new usb-serial device ids and cleanups
- loads of dwc3 controller fixes and improvements
- mtu3 driver updates
- testusb fixes for longtime issues (not many people use this tool it
seems.)
- minor driver fixes and improvements over the USB tree
- chromeos platform driver changes were added and then reverted as
they depened on some typec changes, but the cross-tree merges
caused problems so they will come back later through the platform
tree.
All of these have been in linux-next for a while now with no reported
issues"
