Update the driver to use the new ASoC core control notify helper.
This also fixes a bug where the control would not be found if the
CODEC was given a name prefix.

Apply a workaround for what appears to be a hardware quirk.
The problem seems to happen when enabling "whole chip power" (bit D7
register R6) for the very first time after the chip receives power. If
either "output" (D4) or "DAC" (D3) aren't powered on at that time,
playback becomes very distorted later on.
This happens on the Google Chameleon v3, as well as on a ZYBO Z7-10:
https://ez.analog.com/audio/f/q-a/543726/solved-ssm2603-right-output-offset-issue/480229
I suspect this happens only when using an external MCLK signal (which
is the case for both of these boards).
Here are some experiments run on a Google Chameleon v3. These were run
in userspace using a wrapper around the i2cset utility:
ssmset() {
i2cset -y 0 0x1a $(($1*2)) $2
}
For each of the following sequences, we apply power to the ssm2603
chip, set the configuration registers R0-R5 and R7-R8, run the selected
sequence, and check for distortions on playback.
ssmset 0x09 0x01 # core
ssmset 0x06 0x07 # chip, out, dac
OK
ssmset 0x09 0x01 # core
ssmset 0x06 0x87 # out, dac

R0-R5 and R7-R8, run one of the NOT OK sequences from above, and check

regmap has introduced a maple tree based register cache which makes use of
this more advanced data structure which has been added to the kernel
recently. Maple trees are much flatter than rbtrees, meaning that they do
not grow to such depths when the register map is sparse which makes access
a bit more efficient. The maple tree cache type is still a bit of a work
in progress but should be effective for some devices already.
RT5682 seems like a good candidate for maple tree. It only supports single
register read/write operations so will gain minimal benefit from storing
the register data in device native format like rbtree does (none for
SoundWire) and has some sparsity in the register map which is a good fit
for maple tree.
Convert to use maple tree. There should be little if any visible difference
at runtime.

device and therefore supports only single register read/write operations
which do not use raw I/O and will therefore save the cost of converting
to and from device native format when accessing the cache while not having
a negative impact from the current lack of bulk operations in maple tree
cache sync. It has a moderately large and quite sparse register map which
is a good fit for storing in a maple tree.

Here are collections of small fixes for rc1.
The only (LOC-wise) dominant change was ASoC Qualcomm fix, but most
of it was merely a code shuffling.
Another significant change here is for ALSA PCM core; it received a
revert and a series of fixes for PCM auto-silencing where it caused
a regression in the previous PR for rc1.
Others are all small: ASoC Intel fixes, various quirks for ASoC AMD,
HD-audio and USB-audio, the continued legacy emu10k1 code cleanup,
and some documentation updates.

ASoC: Fixes for v6.4
A small set of fixes and device quirks that have come in during the
merge window, the Qualcomm fix seems quite large but it's mainly code
motion so looks larger than it is.
The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

dsp_ready_completion is redundant and can be replaced by a call
flush_work() to wait for cs35l56_dsp_work() to complete.
As the dsp_work is queued by component_probe() it must run before other
ASoC component callbacks and therefore there is no risk of calling
flush_work() before the dsp_work() has been queued.

Moving the wait from the beginning of the cs35l56_dsp_work() into
cs35l56_component_probe() will prevent the limbo situation that is an
artifact of the two stage SoundWire driver probe and initialisation
where the card is all registered and shows in ALSA but doesn't actually
work because the hardware didn't enumerate.
The other bus drivers perform the probe and init sequentially and are
not susceptible to this issue.

The irq member was being set before calling the init function and then
cs35l56_irq_request() was called only when the init was successful.
However cs35l56_release() calls devm_free_irq() when the irq member is
set and therefore if init() fails then this will cause an attempted free
of an unallocated IRQ.
Instead pass the desired IRQ number to the cs35l56_irq_request()
function and set cs35l56->irq only when it has been successfully
allocated.

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.
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.
If the driver has control of RESET we will have asserted it during
suspend so the firmware patch will have been lost. The driver would only
have control of RESET in non-secure mode.

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.

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

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.

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.

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.
