This patch prepares the introduction of the compress API with SOF.

After each fragment is accepted by the DSP we need to inform
the userspace applications that they can send the next fragment.
This is done via snd_compr_fragment_elapsed.

Similar with the PCM case, in order to avoid sending an IPC before
the previous IPC is handled we need to schedule a delayed work to
call snd_compr_fragment_elapsed().

See snd_sof_pcm_period_elapsed.

To sum up this patch offers the following API to SOF code:
	* snd_sof_compr_init_elapsed_work
	* snd_sof_compr_fragment_elapsed

Note that implementation for compressed function is in a new file
selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option.
This option is automatically selected for platforms that support
the compress interface. For now only i.MX8 platforms support this.

For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup
the work struct for PCM case.

Merge series "ASoC: SOF: Intel: add flags to turn on SSP clocks early" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

With the chip shortage, some GeminiLake Intel-based designs were
respun and now rely on codecs that need the SSP bit clock turned on in
the hw_params stage, not the trigger stage. This patchset mirrors the
flags added in the SOF DAI_CONFIG IPC, and sets the flags when this
capability is indicated as necessary in the topology files where the
SSP configuration is stored.

We initially considered a more generic solution with an on-demand SSP
clock activation using the common clock framework. This would be a
more elegant solution indeed, but it would have required more
intrusive changes that would conflict with the SOF multi-client
support (in-development), and more backport hassles on product
branches. The on-demand activation of clocks is still a desired
feature that will be enabled at a later point.

For debug and community support, it's useful to expose a kernel
parameter to prevent the use of dynamic pipelines exposed in a
topology file, or conversely to force an existing topology to use
dynamic pipelines.

Add an override bit and an enable bit which is valid only when the
override is set.

For products, the intent is that the topology file defines the
behavior, these two bits are only intended for diagnosis and
performance checks.

In order to keep the widget use_count balanced, make sure the DAI
widgets are allocated once in hw_params and released in hw_free. A
'setup' status flag is used to deal with cases where the .hw_params
callback is invoked multiple times, and likewise with cases where
hw_free is invoked without hw_params being called first (which can
happen if the FE hw_params fails).

In addition, this patch frees the widgets in the suspend transition,
and reallocates them in the .prepare callback. The 'setup' flag helps
in this case differentiate between resume (setup needed) and
xruns (setup not needed).

This balanced operation was not needed previously but will be required
when SOF dynamic pipelines are enabled.

Mirror changes done in SOF tree. The changes do not rely on
BIT/GENMASK on purpose to keep the structure and flags common with the
firmware tree.

The DAI_CONFIG IPC is currently used in multiple ways. It is sent to
the DSP firmware when enabling static or dynamic pipelines, in
hw_params or prepare callbacks for Intel SSP, HDaudio and ALH, on
trigger_stop and hw_free.

This IPC has been abused a bit in the past, i.e. the values used for
some of the DAI-specific fields are used to either allocate or free
resources. Two typical examples are Intel HDaudio and SoundWire/ALH
DAIs, where using a zero DMA channel number or stream tag signals to
the firmware the DMA channels or tags allocated earlier can be freed.

Rather than add a new IPC for 'hw_params' and 'hw_free', this patch
suggests supporting a 2-bit value conveying the 'stage' information in
an existing IPC structure. Only 3 possible values are used.

The mapping between HW_PARAMS and HW_FREE flags and ALSA definitions
is not strictly 1:1, e.g. in some cases the HW_PARAM flag might be set
during the .prepare callback, while the HW_FREE might be sent during the
ALSA .trigger for stop/suspend.

The semantics of the flags is to reserve and start/stop all needed
resources, typically hardware related such as DMAs or clocks, when the
HW_PARAMS is set, while the HW_FREE flag allows the firmware to
release the resources allocated. The data transfers are still
controlled within the firmware through the propagation of the trigger
command.

The driver can then pass information that the DAI_CONFIG was invoked
in e.g. a pipeline/DAI setup, hw_params or hw_free stage without
having to use a special DAI-specific encoding. Unfortunately we can't
remove old encodings due to backwards-compatibility requirements but
for new cases, such as the SSP in follow-up patches, we can make the
IPC less cryptic.

This change is tagged as ABI 3.19 and is completely backwards compatible.

https://lore.kernel.org/alsa-devel/20210917143659.401102-1-daniel.baluta@oss.nxp.com/

We have agreed that it might be better that someone from Intel is going to take it
from here as we already have the infrastructure up to test and verify the
dynamic pipelines support.

Changes since v2 (sent by Daniel Baluta):
- patch 10: Fix NULL point dereference in hda_dai_update_config()
- I have kept Daniel's SoB for the series.

Changes since v1:
- Signed-off-by tag added by Daniel

This series implements initial support for dynamic pipelines to setup/teardown
pipeline as needed when a PCM is open/closed.

Initially dynamic pipelines are only supported with single core setup which will
be expanded with a follow-up series.

Review with SOF community at
https://github.com/thesofproject/linux/pull/2794

The feature has been merged on 1st of April to sof-dev, all issues found since
has been fixed and squashed to this upstream series.

Implement SPDIF bypass mode. It implies internal SoC
routing of SPDIF input signal to SPDIF output signal. The
test bed requires two boards: B1 configured in bypass mode,
and B2 to feed B1 SPDIF RX port and read B1 SPDIF TX port:
   B2 TX -> B1 RX,
   B2 RX <- B1 TX.
The test procedure:
 a) Boot both boards
 b) B2: start "arecord <spdifcard> -r 48kHz | aplay <local DAC>"
 c) B2: start "aplay <spdifcard> -r 48kHz <2ch 48kHz audio file>"
 d) B1: enable bypass mode:
	amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' on
 e) B2: check DAC audio, make sure the same sample rate is used at
	steps b) and c), in example above the rate is 48kHz.
 f) B1: try to run "aplay" or "arecord" on imxspdif card while in
	bypass mode - both must fail until bypass mode is disabled
 g) B1: disable bypass mode:
	amixer -cimxspdif cset numid=8,iface=PCM,name='Bypass Mode' off
 h) B1: check the usual playback and capture on imxspdif card.
	During this test try to set bypass mode - must not be allowed
	while playback or capture is running.

Add a kernel debug flag to enable a one-shot topology
verification for all pipelines including the dynamic
ones. If the debug flag is set, all the topology
component loading will be verified during the complete
callback.

Add support for dynamic pipelines by modifying the PCM
hw_params ioctl implementation to determine the widgets
required for a PCM stream by querying the list of
connected DAPM widgets. This list is saved as part of
snd_sof_pcm_stream struct and will be used to setup the widgets.

The sof_widget_list_setup/free routines setup and free connected
DAPM widgets when a PCM is opened/closed. These routines accept
a list of connected DAPM widgets as input and determine the SOF
widgets, their corresponding pipeline widgets and connections
between them that need to be setup before the PCM is triggered.

Please note that the dynamic pipeline feature will only be enabled
for those pipelines whose dynamic_pipeline_widget flag is set in
topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE
that when set in topology will be applied to the
dynamic_pipeline_widget flag of the pipeline widget.

With the implementation of the dynamic pipeline feature, widgets
will only be setup when a PCM is opened during the
hw_params ioctl. The BE hw_params callback is responsible for
sending the DAI_CONFIG for the DAI widgets in the DSP.
With dynamic pipelines, the DAI widgets will need to set up
first before sending the DAI_CONFIG IPC in the BE hw_params.

Update the BE hw_params/hw_free callbacks for all ALH, HDA and SSP
DAIs to set up/free the DAI widget before/after DAI_CONFIG IPC.

Add a new field, use_count to struct snd_sof_widget to keep track
of the usage count for each widget. Since widgets can belong to
multiple pipelines, this field will ensure that the widget
is setup only when the first pipeline that needs it is started
and freed when the last pipeline that needs it is stopped. There is
no need to protect the widget use_count access as the core already
handles mutual exclusion at the PCM level.
Add a new helper sof_widget_free() to handle freeing the SOF
widgets and export the sof_widget_setup/free() functions.

In preparation for supporting dynamic pipelines, move the
widget setup, DAI config IPCs to the complete callback
during topology loading. For current topology where all
the pipelines are static, all the pipelines will be set up
during complete. For topologies with dynamic and static pipelines,
this will enable setting up only the static ones  during
topology loading. Reuse the sof_restore_pipelines() function for
this purpose and rename it to sof_set_up_pipelines().

Add two new fields to save the source widget and sink widget
pointers in struct snd_sof_route to make it easier to look up
routes by source/sink widget. Also, add a flag to indicate
if the route has been set up in the DSP. These will be used
when the dynamic pipeline feature is implemented and routes
will have to be set up at run time.

Also, add a new sof_tear_down_pipelines() callback, that will
used to reset the set up status for all routes during suspend.
