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.

Use of keep-alive (KAE) has resulted in loss of audio on some A750/770
cards as the transition from keep-alive to stream playback is not
working as expected. As there is limited benefit of the new KAE mode
on discrete cards, revert back to older silent-stream implementation
on these systems.

Merge series from Richard Fitzgerald <[email protected]>:
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.

... in wait_for_avail() and snd_pcm_drain().
t was calculated in seconds, so it would be pretty much always zero, to
be subsequently de-facto ignored due to being max(t, 10)'d. And then it
(i.e., 10) would be treated as secs, which doesn't seem right.
However, fixing it to properly calculate msecs would potentially cause
timeouts when using twice the period size for the default timeout (which
seems reasonable to me), so instead use the buffer size plus 10 percent
to be on the safe side ... but that still seems insufficient, presumably
because the hardware typically needs a moment to fire up. To compensate
for this, we up the minimal timeout to 100ms, which is still two orders
of magnitude less than the bogus minimum.
substream->wait_time was also misinterpreted as jiffies, despite being
documented as being in msecs. Only the soc/sof driver sets it - to 500,
which looks very much like msecs were intended.
Speaking of which, shouldn't snd_pcm_drain() also use substream->
wait_time?
As a drive-by, make the debug messages on timeout less confusing.

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.

This helper is an optimization where sync_go is only called when the
cmdsync field is actually set to a non-zero value.
Since this is also only used by SoundWire for now, only expose the
_unlocked version.

The multi-link synchronization uses the same concept and registers,
but moved to the HDAudio extended links.
Add helpers for sync_arm and sync_go which are the basic for the bus
reset, bank switch and clock stop.
Since SoundWire is the only user of those helpers, only expose the
_unlocked versions for now.
Note that SYNCGO is a write-only bit, so no error can be reported. We
still return 0 for compatibility with the SoundWire stream management
headers.
