dmaengine: remove slave_id config field

All references to the slave_id field have been removed, so remove the
field as well to prevent new references from creeping in again.

Originally this allowed slave DMA drivers to configure which device
is accessed with the dmaengine_slave_config() call, but this was
inconsistent, as the same information is also passed while requesting
a channel, and never changes in practice.

In modern kernels, the device is always selected when requesting
the channel, so the .slave_id field is no longer useful.

dmaengine: xilinx_dpdma: stop using slave_id field

The display driver wants to pass a custom flag to the DMA engine driver,
which it started doing by using the slave_id field that was traditionally
used for a different purpose.

As there is no longer a correct use for the slave_id field, it should
really be removed, and the remaining users changed over to something
different.

The new mechanism for passing nonstandard settings is using the
.peripheral_config field, so use that to pass a newly defined structure
here, making it clear that this will not work in portable drivers.

dmaengine: qcom-adm: stop abusing slave_id config

The slave_id was previously used to pick one DMA slave instead of another,
but this is now done through the DMA descriptors in device tree.

For the qcom_adm driver, the configuration is documented in the DT
binding to contain a tuple of device identifier and a "crci" field,
but the implementation ends up using only a single cell for identifying
the slave, with the crci getting passed in nonstandard properties of
the device, and passed through the dma driver using the old slave_id
field. Part of the problem apparently is that the nand driver ends up
using only a single DMA request ID, but requires distinct values for
"crci" depending on the type of transfer.

Change both the dmaengine driver and the two slave drivers to allow
the documented binding to work in addition to the ad-hoc passing
of crci values. In order to no longer abuse the slave_id field, pass
the data using the "peripheral_config" mechanism instead.

ASoC : soc-pcm: fix trigger race conditions with shared BE

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

We've been adding a 'deep buffer' PCM device to several SOF topologies
in order to reduce power consumption. The typical use-case would be
music playback over a headset: this additional PCM device provides
more buffering and longer latencies, leaving the rest of the system
sleep for longer periods. Notifications and 'regular' low-latency
audio playback would still use the 'normal' PCM device and be mixed
with the 'deep buffer' before rendering on the headphone endpoint. The
tentative direction would be to expose this alternate device to
PulseAudio/PipeWire/CRAS via the UCM SectionModifier definitions.

That seemed a straightforward topology change until our automated
validation stress tests started reporting issues on SoundWire
platforms, when e.g. two START triggers might be send and conversely
the STOP trigger is never sent. The SoundWire stream state management
flagged inconsistent states when the two 'normal' and 'deep buffer'
devices are used concurrently with rapid play/stop/pause monkey
testing.

Looking at the soc-pcm.c code, it seems that the BE state
management needs a lot of love.

a) there is no consistent protection for the BE state. In some parts
of the code, the state updates are protected by a spinlock but in the
trigger they are not. When we open/play/close the two PCM devices in
stress tests, we end-up testing a state that is being modified. That
can't be good.

b) there is a conceptual deadlock: on stop we check the FE states to
see if a shared BE can be stopped, but since we trigger the BE first
the FE states have not been modified yet, so the TRIGGER_STOP is never
sent.

This patchset suggests the removal of the dedicated 'dpcm_lock' and
follows the design suggested by Takashi Iwai.  By default the
protection relies on the 'pcm_mutex', except for the FE and BE
triggers where the mutex cannot be used.  In this case, the FE PCM
lock is used instead. In the cases where a BE is added/removed, the
pcm_mutex and FE PCM lock are both taken.  In addition, the BE PCM
lock is used to serialize access to a shared BE.

With these patches I am able to run our entire validation suite
without any issues with this new 'deep buffer' topology, and no
regressions on existing solutions [1]. The tests were reproduced by
Bard Liao for SoundWire devices.

One might ask 'how come we didn't see this earlier'? The answer is
probably that the .trigger callbacks in most implementations seems to
perform DAPM operations, and sending the triggers multiple times is
not an issue. In the case of SoundWire, we do use the .trigger
callback to reconfigure the bus using the 'bank switch' mechanism. It
could be acceptable to tolerate a trigger multiple times, but the
deadlock on stop cannot be fixed at the SoundWire level alone.

Opens:

1) The issues reported by Nvidia on the RFCv3 may or may not be
present. We'd need test results to make sure the locking update does
not introduce a regression on Tegra.

2) There are other reports of kernel oopses [2] that seem related to
the lack of protection. I'd be good to confirm if this patchset solve
these problems as well.

ASoC: soc-pcm: fix BE handling of PAUSE_RELEASE

A BE connected to more than one FE, e.g. in a mixer case, can go
through the following transitions.

play FE1    -> BE state is START
pause FE1   -> BE state is PAUSED
play FE2    -> BE state is START
stop FE2    -> BE state is STOP (see note [1] below)
release FE1 -> BE state is START
stop FE1    -> BE state is STOP

play FE1    -> BE state is START
pause FE1   -> BE state is PAUSED
play FE2    -> BE state is START
release FE1 -> BE state is START
stop FE2    -> BE state is START
stop FE1    -> BE state is STOP

play FE1    -> BE state is START
play FE2    -> BE state is START (no change)
pause FE1   -> BE state is START (no change)
pause FE2   -> BE state is PAUSED
release FE1 -> BE state is START
release FE2 -> BE state is START (no change)
stop FE1    -> BE state is START (no change)
stop FE2    -> BE state is STOP

The existing code for PAUSE_RELEASE only allows for the case where the
BE is paused, which clearly would not work in the sequences above.

Extend the allowed states to restart the BE when PAUSE_RELEASE is
received, and increase the refcount if the BE is already in START.

[1] the existing logic does not move the BE state back to PAUSED when
the FE2 is stopped. This patch does not change the logic; it would be
painful to keep a history of changes on the FE side, the state machine
is already rather complicated with transitions based on the last BE
state and the trigger type.

ASoC: soc-pcm: test refcount before triggering

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.

For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.

This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by the BE PCM
stream lock.

ASoC: soc-pcm: serialize BE triggers

the BE can be triggered multiple times when the FE are opened/started

the FE, so that there is no deadlock between FE and BE locks.

ASoC: soc-pcm: Fix and cleanup DPCM locking

The existing locking for DPCM has several issues
a) a confusing mix of card->mutex and card->pcm_mutex.
b) a dpcm_lock spinlock added inconsistently and on paths that could
be recursively taken. The use of irqsave/irqrestore was also overkill.

The suggested model is:

1) The pcm_mutex is the top-most protection of BE links in the FE. The
pcm_mutex is applied always on either the top PCM callbacks or the
external call from DAPM, not taken in the internal functions.

2) the FE stream lock is taken in higher levels before invoking
dpcm_be_dai_trigger()

3) when adding and deleting a BE, both the pcm_mutex and FE stream
lock are taken.

ASoC: soc-pcm: align BE 'atomicity' with that of the FE

Since the flow for DPCM is based on taking a lock for the FE first, we
need to make sure during the connection between a BE and an FE that
they both use the same 'atomicity', otherwise we may sleep in atomic
context.

If the FE is nonatomic, this patch forces the BE to be nonatomic as
well. That should have no negative impact since the BE 'inherits' the
FE properties.

However, if the FE is atomic and the BE is not, then the configuration
is flagged as invalid.

ASoC: dt-bindings: qcom: Document qcom,msm8916-qdsp6-sndcard compatible

There are two possible audio setups on MSM8916/APQ8016: Normally the audio
is routed through the audio/modem DSP (covered by the qdsp6 driver). During
upstreaming for the DragonBoard 410c it was decided to bypass it and
instead talk directly to the audio controller using the "lpass" driver.

Bypassing the DSP gives more control about the audio configuration but limits
the functionality: For example, routing audio through the audio/modem DSP is
strictly required for voice call audio. Also, without the special changes in
the DB410c firmware other MSM8916 devices can only use the bypass as long as
the modem DSP is not started. Otherwise, the firmware will assume control of
the LPASS hardware block and audio is no longer functional.

Add support for using the DSP audio setup instead using a new
"qcom,msm8916-qdsp6-sndcard" compatible. It is basically a mixture of
the apq8016-sbc-sndcard and the newer sm8250-sndcard, which uses
indirect QDSP6 DAI links instead of the direct LPASS DAI links.

The sm8250 audio driver uses the common Qualcomm device tree parser and
therefore already supports the "aux-devs" property that allows adding
additional auxiliary devices to the sound card (e.g. analog speaker
amplifiers that can be connected using "audio-routing").

Document the property in the DT schema for sm8250 as well. The description
is taken from simple-card.yaml which has a very similar property.

ASoC: dt-bindings: qcom: sm8250: Drop redundant MultiMedia routes

The MultiMedia audio routes can be deduced from other parts of the
device tree (e.g. the definitions of the MultiMedia DAIs) and therefore
specifying them again in "audio-routing" is redundant and prone to
mistakes. This is no longer necessary since commit 6fd8d2d275f7
("ASoC: qcom: qdsp6: Move frontend AIFs to q6asm-dai").

Let's drop them from the example in the DT schema as well
to avoid confusion.

The code inherited from the Skylake driver does not seem to follow any

The only two recommended options are
a) use DPIB registers if VC1 traffic is not allowed
b) use DPIB DDR update if VC1 traffic is used

In all of SOF-based updated, VC1 is not supported so we can 'safely'
move to using DPIB registers only.

This patch keeps the legacy code, in case there was an undocumented

ASoC: tegra: Add master volume/mute control support

The MVC module has a per channel control bit, based on which it decides
to apply channel specific volume/mute settings. When per channel control
bit is enabled (which is the default HW configuration), all MVC channel
volume/mute can be independently controlled. If the control is disabled,
channel-0 volume/mute setting is applied by HW to all remaining channels.
Thus add support to leverage this HW feature by exposing master controls
for volume/mute.

With this, now there are per channel and master volume/mute controls.
Users need to just use controls which are suitable for their applications.
The per channel control enable/disable is mananged in driver and hidden
from users, so that they need to just worry about respective volume/mute
controls.

ASoC: SOF: Intel: Retry codec probing if it fails

On the latest Lenovo Thinkstation laptops, we often experience the
speaker failure after rebooting, check the dmesg, we could see:
 sof-audio-pci-intel-tgl 0000:00:1f.3: codec #0 probe error, ret: -5

The analogue codec on the machine is ALC287, then we designed a
testcase to reboot and check the codec probing result repeatedly, we
found the analogue codec probing always failed at least once within
several minutes to several hours (roughly 1 reboot per min). This
issue happens on all laptops of this Thinkstation model, but with
legacy HDA driver, we couldn't reproduce this issue on those laptops.
And so far, this issue is not reproduced on machines which don't
belong to this model.

We tried to make the hda_dsp_ctrl_init_chip() same as
hda_intel_init_chip() which is the controller init routine in the
legacy HDA driver, but it didn't help.

We found when issue happens, the resp is -1, and if we let driver
re-run send_cmd() and get_response(), it will get the correct response
10ec0287, then driver continues the rest work, finally boot to the
desktop and all audio function work well.

Here adding codec probing retries to 3 times, it could fix the issue
on this Thinkstation model, and it doesn't bring impact to other
machines.
