The only other way to catch these would have been to monitor
the Tx deauth event, but we can send a deauth when we roam.
So it would have been tricky to make sure we capture the
connection losses only.
Define a separate trigger for the connection losses to make
it easier to catch them.

The current code has a lot of duplicates of printing into a buffer
(while having to make sure it's NUL-filled and -terminated) and
then passing that to the debug trigger collection.
Since that's error-prone, instead make the debug trigger collection
function take a format string and format arguments (with compiler
validity checking) and handle the buffer internally.
This makes one behavioural change -- instead of sending the whole
buffer to userspace (clearing is needed to not leak stack data) it
just passes the actual string (including NUL-terminator.)

Sending multiple action frames off channel, one after the other can create
a race that will result in a timeout:
1. Start sending action frame off channel.
2. Once the frame is sent or the time event is over, the flow will
eventually call ieee80211_start_next_roc to start the next roc frame &
iwl_mvm_roc_finished schedules to schedule a work to flush the queue.
3. Start sending new roc frame and write it to the queue before the
flush work has started.
4. The work is called and it flushes the new packet that was placed on the
on the queue so the packet is lost.
This causes the frame to be removed & not sent, that causes a timeout in
userspace.
Flush the work queue that flushes the roc/off channel queue before starting
to send a new frame off channel, in order to avoid a race between the new
frame that is transmitted off channel & the flushing of the queue.

====================
DSA Mavell drivers refactoring and cleanup
v1->v2:
* Add missing signed-of-by: For patches authored by Guenter Roeck.
* Add Reviewed by from Guenter Roack to patch #5.
This is a collection of patches again net-next from today containing
refactoring and consolidate of code, cleanups and using #define's to
replace register numbers.
Patch #1 Swaps the 6131 driver to use the consolidated setup code.
Patch #2 Moves the Switch IDs used during probe into a central
location. We need these later so that we can differentiate
the different features the devices have.
Patch #3 Makes the 6131 driver set the number of ports in the private
state structure. It then uses this, rather than hard coded
maximum number of ports.
Patch #4 Similar to Patch #3, but for the 6123_61_65 driver.
Patch #5 Similar to Patch #3, and #4, but for all the remaining
drivers. This greatly increases the similarity of the code
between drivers, allow further patches to consolidate the
duplicated code.
Patch #6 Consolidate the switch reset code, which has two minor
variants. Removes around 35 lines per driver.
Patch #7 Moves phy page access functions out of the 6352 driver into
the shared code. Currently only the 6352 driver uses this,
but it is likely other devices will come along wanting this
functionality.
Patch #8 Consolidates the code used to access phy registers. Removes
around 40 lines of code per driver.
Patch #9 Fixes missing mutex locking in the EEE code, and refactors
the code a bit to make it more understandable with respect to
locks.
Patch #10 Consolidates reading statistics. This is very similar code
for all devices, but the number of available statistics
differ, which can be determined from the product ID. Removes
around 65 lines per driver.
Patch #11 Add #defines for registers, and bits within the
registers. For the moment, this is limited to the shared
code. The individual drivers will be converted once the
remaining duplicated code is consolidated
Patch #12 Fix broken statistic counters on the 6172. The 6352 family
requires the port number is poked into a different set of
bits in the register compared to other devices.
Many thanks to Guenter Roeck for repeatedly reviewing the patches and
testing them on his hardware.

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
Audio DMAC peri peri DMAEngine is no longer needed.

as the act8865/act8846 driver gained supply handling in the regulator tree.

Add acpu driver for hisilicon SoC, acpu is application processor
subsystem. Currently the acpu has the coupled clock domain for two
clusters, so this driver will directly use cpufreq-dt driver as
backend.

On some machines(E,G Mircosoft surface 3), ACPI battery depends on
the EC operation region and it has _DEP method which contains EC.
Current code doesn't support such devices whose dep_unmet will be
not be decreased after EC opregion handler being installed. This
blocks battery device to be attached with its driver. This patch
is to fix the issue.
