ASoC: expand snd_soc_dapm_mutex_lock/unlock()

soc.h has snd_soc_dapm_mutex_lock/unlock() definition and
many drivers are using it, but soc-dapm.c is not.

1st reason is snd_soc_dapm_mutex_lock/unlock() requests
snd_soc_dapm_context pointer as parameter (A), but sometimes soc-dapm.c
needs to use snd_soc_card (B).

(A) static inline void snd_soc_dapm_mutex_lock(struct snd_soc_dapm_context *dapm)
{
mutex_lock_nested(&dapm->card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
}    ^^^^^^^^^^

(B) mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
   ^^^^

2nd reason is it want to use SND_SOC_DAPM_CLASS_INIT for mutex_lock_nested(),
but helper is using _RUNTIME (A).

The conclusion is we want to use "dapm vs card" and "_RUNTIME vs _INIT"
for dapm lock/unlock. To enable this selfish request, this patch uses
_Generic macro. We can use snd_soc_dapm_mutex_lock/unlock() for both
dapm and card case.

snd_soc_dapm_mutex_lock(dapm); snd_soc_dapm_mutex_unlock(dapm);
snd_soc_dapm_mutex_lock(card); snd_soc_dapm_mutex_unlock(card);

Current soc-dapm.c is using both mutex_lock() and mutex_lock_nested().
This patch handles mutex_lock() as mutex_lock_nested(..., 0),
in other words, handles below as same.

mutex_lock(&card->dapm_mutex);
mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_INIT);

Because people might misunderstand that _init() is mutex initialization,
this patch renames _INIT to _ROOT and adds new
snd_soc_dapm_mutex_lock_root() for it.

This patch also moves snd_soc_dapm_subclass definition from soc-dapm.h
to soc.h to keep related code together.

Because very complex soc.h vs soc-dapm.h relationship,
it is difficult/impossible to define these helper into soc-dapm.h.

ASoC: cs35l56: Add system suspend handling

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:

This set of patches adds handling for system suspend.
Patches 1..4 make some code changes that simplify the
suspend implementation, mainly to avoid race conditions.

There are two seperate aspects to suspend, and these have
been done as two patches:
- the main suspend-resume handling,
- re-loading the firmware if necessary after resume.

ASoC: cs35l56: Re-patch firmware after system suspend

Check during cs35l56_system_resume() whether the firmware patch must
be applied again.

The FIRMWARE_MISSING flag in the PROTECTION_STATUS register indicates
whether the firmware has been patched.

In non-secure mode the FIRMWARE_MISSING flag is cleared at the end of
dsp_work(). If it is set after system-resume we know that dsp_work()
must be run again.

In secure mode the pre-OS loader will have done the secure patching
and cleared the FIRMWARE_MISSING flag. So this flag does not tell us
whether firmware memory was lost. But the driver could only be
downloading non-secure tunings, which is always safe to do.

ASoC: cs35l56: Remove quick-cancelling of dsp_work()

Delete the 'removing' flag and don't kick init_completion to make a
quick cancel of dsp_work(). Just let it timeout on the wait for the
completion.

Simplify the code to standard cancelling or flushing of the work.
This avoids introducing corner cases from a layer of custom signalling.
It also avoids potential race conditions when system-suspend handling
is added.

Unless the hardware is broken, the dsp_work() will already have started
and passed the completion before the driver would want to cancel it.

ASoC: cs35l56: Add basic system suspend handling

This adds the main handling for system suspend but does not handle
re-patching the firmware after system resume.

This is a multi-stage suspend and resume because if there is a
RESET line it is almost certain that it will be shared by all the
amps. So every amp must have done its suspend before we can
assert RESET. Likewise we must de-assert RESET before the amps
can resume.

It's preferable to assert RESET before we turning off regulators, and
while they power up.

The actual suspend and resume is done by using the pair
pm_runtime_force_suspend() and pm_runtime_force_resume() to
re-use our runtime suspend/resume sequences.

pm_runtime_force_suspend() will disable our pm_runtime. If we were
runtime-resumed it calls our runtime_suspend().

pm_runtime_force_resume() re-enables pm_runtime and if we were
originally runtime-resumed before the pm_runtime_force_suspend()
it calls our runtime_resume(). Otherwise it leaves us
runtime-suspended.

The general process is therefore:

 suspend() -> finish dsp_work and then run our runtime_suspend
 suspend_late() -> assert RESET and turn off supplies
 resume_early() -> enable supplies and de-assert RESET
 resume() -> pm_runtime_force_resume()

In addition, to prevent the IRQ handler running in the period
between pm_runtime_force_suspend() and pm_runtime_force_resume()
the parent IRQ is temporarily disabled:
 - from suspend until suspend_noirq
 - from resume_noirq until resume

ASoC: cs35l56: Always wait for firmware boot in runtime-resume

When we are resuming from a system suspend the CS35L56 has probably
been hard reset (usually a power-on reset). So we must wait for the
firmware to boot. On SoundWire we also need it to re-initialize before
we can read the registers to check the CS35L56 state.

The simplest way to handle this is for runtime-resume to always wait
for firmware boot. If the firmware is already booted the overhead is
only one register read.

The system-resume will have to runtime-resume the driver anyway before
attempting any register access. So this will automatically include the
wait for initialization on SoundWire.

ASoC: cs35l56: Skip first init_completion wait in dsp_work if init_done

At the start of dsp_work() only wait for init_completion if !init_done.
This allows system suspend to re-queue dsp_work() without having to
do a dummy complete() of init_completion.

A dummy completion in system suspend would have to be conditional on
init_done. But that would create a possible race condition between our
system resume and cs35l56_init() in the corner case that we suspend right
after the SoundWire core has enumerated and reported ATTACHED.

It is safer and simpler to have cs35l56_init() as the only place that
init_completion is completed, and dsp_work() as the only place that
it is consumed.

ASoC: cs35l56: Use DAPM widget for firmware PLAY/PAUSE

If we use a DAPM widget instead of mute_stream() to send the
PLAY command we can issue the plays to multiple amps in parallel.
With mute_stream each codec driver instance is called one at a
time so we get N * PS0 delay time.

DAPM does each stage on every widget in a card before moving to
the next stage. So all amps will do the PRE_PMU then all will do
the POST_PMU. The PLAY is sent in the PRE_PMU so that they all
power-up in parallel. After the PS0 wait in the first POST_PMU
all the other amps will also be ready so there won't be any extra
delay, or it will be negligible.

There's also no point waiting for the MBOX ack in the PRE_PMU.
We won't see a PS0 state in POST_PMU if it didn't ack the PLAY
command. So we can save a little extra time.

ASoC: SOF: Intel: hda-mlink: program SoundWire LSDIID registers

Each SoundWire peripheral can be programmed from the manager side
either with a regular command FIFO, or with the HDaudio CORB/RIRB
DMA-based mechanism. The mapping between SoundWire peripheral and SDI
address is handled with the LSDIID register.

This mapping only works of course if each peripheral has a unique
address across all links. This has already been enforced in previous
Intel contributions allowing for an IDA-based solution for the device
number allocation.

The checks on the dev_num are handled at the SoundWire level, but the
locking is handled at the hda-mlink level.

These helpers configure the ratio between the base clock and the

aligned with hardware recommendations. If desired, this helper could

ASoC: SOF: Intel: hda-mlink: introduce helpers for 'extended links' PM

Add helpers to program SPA/CPA bits, using a mutex to access the
shared LCTL register if required.

All links are managed with the same LCTLx.SPA bits. However there are
quite a few implementation details to be aware of:

Legacy HDaudio multi-links are powered-up when exiting reset, which
requires the ref_count to be manually set to one when initializing the
link.

Alternate links for SoundWire/DMIC/SSP need to be explicitly
powered-up before accessing the SHIM/IP/Vendor-Specific SHIM space for
each sublink. DMIC/SSP/SoundWire are all different cases with a
different device/dai/hlink relationship.

SoundWire will handle power management with the auxiliary device
resume/suspend routine. The ref_count is not necessary in this case.

The DMIC/SSP will by contrast handle the power management from DAI
.startup and .shutdown callbacks.

The SSP has a 1:1 mapping between sublink and DAI, but it's
bidirectional so the ref_count will help avoid turning off the sublink
when one of the two directions is still in use.

The DMIC has a single link but two DAIs for data generated at
different sampling frequencies, again the ref_count will make sure the
two DAIs can be used concurrently.

And last the SoundWire Intel require power-up/down and bank switch to
be handled with a lock already taken, so the 'eml_lock' is made
optional with the _unlocked versions of the helpers.

Note that the _check_power_active() implementation is similar to
previous helpers in sound/hda/ext, with sleep duration and timeout
aligned with hardware recommendations. If desired, this helper could
be modified in a second step with .e.g. readl_poll_timeout()

ASoC: clarify Codec2Codec params

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

ASoC is supporting Codec2Codec, but its parameter name is
"params" and "num_params" which are very unclear naming.

This patch-set clarifies it by replacing to c2c_params / num_c2c_params.

ASoC: SOF: core/Intel: Introduce DSPless mode

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

This series will add support for SOF Linux stack to run without using the DSP.

DSPless mode provides a good tool for verification that the hardware itself
works correctly by taking the DSP use out from the picture.
It can only work with interfaces which supports this mode: Intel HDA at the
moment but with LNL it could be possible to support other audio interfaces.

The main driver for this mode is to be able to test programming sequences,
low-level code and for low-level verification of a platform.

The feature is not targetted for end-users and it will not make the SOF stack
to work on hardware without DSP, but it is giving us a tool to debug and enable
platforms earlier (when for example t he firmware is not mature enough).

ASoC: tegra20_ac97: Add missing unwind goto in tegra20_ac97_platform_probe()

Smatch Warns:
sound/soc/tegra/tegra20_ac97.c:321 tegra20_ac97_platform_probe()
warn: missing unwind goto?

The goto will set the "soc_ac97_ops" and "soc_ac97_bus" operations to
NULL.  But they are already NULL at this point so it is a no-op.
However, just for consistency, change the direct return to a goto.  No
functional change.
