ASoC: Fixes for v6.4

A collection of fixes for v6.4, mostly driver specific but there's also
one fix for DPCM to avoid incorrectly repeated calls to prepare() which
can trigger issues on some systems.

It happens because of play_dma_data/capture_dma_data pointers are NULL.
Current implementation assigns these pointers at snd_soc_dai_driver
startup() callback and reset them back to NULL at shutdown(). But
soc_pcm_open() sequence uses DMA pointers in dmaengine_pcm_open()
before snd_soc_dai_driver startup().
Most generic DMA capable I2S drivers use snd_soc_dai_driver probe()
callback to init DMA pointers only once at probe. So move DMA init
to dw_i2s_dai_probe and drop shutdown() and startup() callbacks.

Merge series from Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>:

Series of fixes for issues found during development and testing,
primarly for avs driver.

It's reported that the recording started right after the driver probe
doesn't work properly, and it turned out that this is related with the
codec auto-suspend.  Namely, after the probe phase, the usage count
goes zero, and the auto-suspend is programmed, but the codec is kept
still active until the auto-suspend expiration.  When an application
(e.g. alsactl) updates the mixer values at this moment, the values are
cached but not actually written.  Then, starting arecord thereafter
also results in the silence because of the missing unmute.

The root cause is the handling of "lazy update" mode; when a mixer
value is updated *after* the suspend, it should update only the cache
and exits.  At the resume, the cached value is written to the device,
in turn.  The problem is that the current code misinterprets the state
of auto-suspend as if it were already suspended.

Although we can add the check of the actual device state after
pm_runtime_get_if_in_use() for catching the missing state, this won't
suffice; the second call of regmap_update_bits_check() will skip
writing the register because the cache has been already updated by the
first call.  So we'd need fixes in two different places.

OTOH, a simpler fix is to replace pm_runtime_get_if_in_use() with
pm_runtime_get_if_active() (with ign_usage_count=true).  This change
implies that the driver takes the pm refcount if the device is still
in ACTIVE state and continues the processing.  A small caveat is that
this will leave the auto-suspend timer.  But, since the timer callback
itself checks the device state and aborts gracefully when it's active,
this won't be any substantial problem.

Long story short: we address the missing register-write problem just
by replacing the pm_runtime_*() call in snd_hda_keep_power_up().

In the BE hw_params configuration, the existing code checks if any of the
existing FEs are prepared, running, paused or suspended - and skips the
configuration in those cases. This allows multiple calls of hw_params
which the ALSA state machine supports.

This check is not handled for the prepare stage, which can lead to the
same BE being prepared multiple times. This patch adds a check similar to
that of the hw_params, with the main difference being that the suspended
state is allowed: the ALSA state machine allows a transition from
suspended to prepared with hw_params skipped.

This problem was detected on Intel IPC4/SoundWire devices, where the BE
dailink .prepare stage is used to configure the SoundWire stream with a
bank switch. Multiple .prepare calls lead to conflicts with the .trigger
operation with IPC4 configurations. This problem was not detected earlier
on Intel devices, HDaudio BE dailinks detect that the link is already
prepared and skip the configuration, and for IPC3 devices there is no BE
trigger.

The rt5682 driver switches its regmap to cache-only when the
device suspends and back to regular mode on resume. When the
jack detect interrupt fires rt5682_irq() schedules the jack
detect work. This can result in invalid reads from the regmap
in cache-only mode if the work runs before the device has
resumed:

[   56.245502] rt5682 9-001a: ASoC: error at soc_component_read_no_lock on rt5682.9-001a for register: [0x000000f0] -16

Disable the jack detection interrupt during suspend and
re-enable it on resume. The driver already schedules the
jack detection work on resume, so any state change during
suspend is still handled.

This is essentially the same as commit f7d00a9b ("SoC:
rt5682s: Disable jack detection interrupt during suspend")
for the rt5682s.

ASoC: Fixes for v6.4

More fixes that came in since the merge window, the bulk of which are
for the SOF code, I suspect as a result of the wide usage, active
development and large code size rather than huge quality problems.

There's also a couple of MAINTAINERS updates and some new device quirks.

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

With additional testing with multiple links and multiple DAI types, we
found a couple of mistakes with refcounts, base address, missing
initialization.

A new helper was also added due to a change in the SoundWire
programming sequences, with the host driver in charge of setting up
the DMA channel mapping instead of the firmware.

The memory allocated for the tuples array assumes that there's 1
instance of all tokens already. So for those tokens that have multiple
instances in topology, we need to exclude the initial instance that has
already been accounted for.

If there are failures in DSP runtime resume, the device state will not
reach active and this makes it impossible e.g. to retrieve a possible
DSP panic dump via "exception" debugfs node. If
CONFIG_SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE=y is set, the data in
cache is stale. If debugfs cache is not used, the region simply cannot
be read.

To allow debugging these scenarios, update the debugfs cache contents in
resume error handler. User-space can then later retrieve DSP panic and
other state via debugfs (requires SOF debugfs cache to be enabled in
build).

When devm runs function in the "remove" path for a device it runs them
in the reverse order. That means that if you have parts of your driver
that aren't using devm or are using "roll your own" devm w/
devm_add_action_or_reset() you need to keep that in mind.

The mt8186 audio driver didn't quite get this right. Specifically, in
mt8186_init_clock() it called mt8186_audsys_clk_register() and then
went on to call a bunch of other devm function. The caller of
mt8186_init_clock() used devm_add_action_or_reset() to call
mt8186_deinit_clock() but, because of the intervening devm functions,
the order was wrong.

Specifically at probe time, the order was:
1. mt8186_audsys_clk_register()
2. afe_priv->clk = devm_kcalloc(...)
3. afe_priv->clk[i] = devm_clk_get(...)

At remove time, the order (which should have been 3, 2, 1) was:
1. mt8186_audsys_clk_unregister()
3. Free all of afe_priv->clk[i]
2. Free afe_priv->clk

The above seemed to be causing a use-after-free. Luckily, it's easy to
fix this by simply using devm more correctly. Let's move the
devm_add_action_or_reset() to the right place. In addition to fixing
the use-after-free, code inspection shows that this fixes a leak
(missing call to mt8186_audsys_clk_unregister()) that would have
happened if any of the syscon_regmap_lookup_by_phandle() calls in
mt8186_init_clock() had failed.

The commands in sof_ipc_dai_config.flags are encoded as bits:
1 (bit0) - hw_params
2 (bit1) - hw_free
4 (bit2) - pause

These are commands, they cannot be combined as one would assume, for
example
3 (bit0 | bit1) is invalid.

This can happen right at the second start of a stream as at the end of the
first stream we set the hw_free command (bit1) and on the second start we
would OR on top of it the hw_params (bit0).

When a firmware IPC error happens during a pm_runtime suspend, we
ignore the error and suspend anyways. However, the code
unconditionally increases the runtime_pm counter. This results in a
confusing configuration where the code will suspend, resume but never
suspend again due to the use of pm_runtime_get_noresume().

The intent of the counter increase was to prevent entry in D3, but if
that transition to D3 is already started it cannot be stopped. In
addition, there's no point in that case in trying to prevent anything,
the firmware error is handled and the next resume will re-initialize
the firmware completely.

This patch changes the logic to prevent suspend when the device is
pm_runtime active and has a use_count > 0.

These registers enable the HDaudio DMA hardware to split/merge data
from different PDIs, possibly on different links.

This capability exists for all types of HDaudio extended links, but
for now is only required for SoundWire. In the SSP/DMIC case, the IP
is programmed by the DSP firmware.
