Merge tag 'usb-6.16-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 6.16-rc1.
Included in here are the following:

- USB offload support for audio devices.

I think this takes the record for the most number of patch series
(30+) over the longest period of time (2+ years) to get merged
properly.

Many props go to Wesley Cheng for seeing this effort through, they
took a major out-of-tree hacked-up-monstrosity that was created by
multiple vendors for their specific devices, got it all merged into
a semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees.

This feature offers major power savings on embedded devices where a
USB audio stream can continue to flow while the rest of the system
is sleeping, something that devices running on battery power really
care about. There are still some more small tweaks left to be done
here, and those patches are still out for review and arguing among
the different hardware companies, but this is a major step forward
and a great example of how to do upstream development well.

- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)

- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly

- typec driver updates

- USB3 power management reworking and updates

- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added
for the USB offload feature.

- lots of little updates and fixes in different drivers

All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues"

ASoC: usb: Rediscover USB SND devices on USB port add

In case the USB backend device has not been initialized/probed, USB SND
device connections can still occur. When the USB backend is eventually
made available, previous USB SND device connections are not communicated to
the USB backend. Call snd_usb_rediscover_devices() to generate the connect
callbacks for all USB SND devices connected. This will allow for the USB
backend to be updated with the current set of devices available.

The chip array entries are all populated and removed while under the
register_mutex, so going over potential race conditions:

Thread#1:
q6usb_component_probe()
--> snd_soc_usb_add_port()
--> snd_usb_rediscover_devices()
--> mutex_lock(register_mutex)

Thread#2
--> usb_audio_disconnect()
--> mutex_lock(register_mutex)

So either thread#1 or thread#2 will complete first. If

Thread#1 completes before thread#2:
SOC USB will notify DPCM backend of the device connection. Shortly
after, once thread#2 runs, we will get a disconnect event for the
connected device.

Thread#2 completes before thread#1:
Then during snd_usb_rediscover_devices() it won't notify of any
connection for that particular chip index.

ASoC: usb: Fetch ASoC card and pcm device information

USB SND needs to know how the USB offload path is being routed. This would
allow for applications to open the corresponding sound card and pcm device
when it wants to take the audio offload path. This callback should return
the mapped indexes based on the USB SND device information.
