Merge tag 'usb-6.7-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 USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for
new hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio,
spi, and i2c drivers for that type of device (all acked by the
respective subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems"
