ASoC: SOF: debug: Swap the dsp_dump and ipc_dump sequence for fw_exception
snd_sof_dsp_panic() only prints dsp_dump followed by flushing the DMA trace
buffer.

To retain similar 'sequence' first do an ipc_dump then the dsp_dump and
finally flush the trace buffer in case of fw_exception.

ASoC: SOF: core: debug: force all processing on primary core
The topology file currently provides information on which
pipeline/processing is to be scheduled on which DSP core.

To help diagnose potential issues, this patch provides an override of
the 'core' tokens to use the primary core (typically core0). Of course
this may result in a Core0 activity that exceeds hardware
capabilities, so this should only be used when the total processing
fits on DSP - possibly using firmware mockup processing and stubs.

No new dmesg log was added to avoid adding noise during topology
parsing, but the existing logs will show the primary core being used.

This is strictly for validation/debug, products should NEVER use this
override, the topology is assumed to be the description of the
firmware graph.

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.

ASoC: SOF: topology: allow for dynamic pipelines override for debug
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.

ASoC: SOF: Intel: hda-dai: improve SSP DAI handling for dynamic pipelines
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.

ASoC: SOF: dai: include new flags for DAI_CONFIG
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.

This is done inside the codec driver because the codec driver already

ASoC: rt5651: Use IRQF_NO_AUTOEN when requesting the IRQ
Use the new IRQF_NO_AUTOEN flag when requesting the IRQ, rather then
disabling it immediately after requesting it.

This fixes a possible race where the IRQ might trigger between requesting

Merge series "Add support for on demand pipeline setup/destroy" from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
Hi,

The previous, v2 of this series was sent by Daniel Baluta:
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.

Regards,
Peter

ASoC: fsl_spdif: implement bypass mode from in to out
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.

ASoC: SOF: Add support for dynamic pipelines
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.

ASoC: SOF: Intel: hda: make sure DAI widget is set up before IPC
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.

ASoC: SOF: topology: Add new token for dynamic pipeline
Today, we set up all widgets required for all PCM streams
at the time of topology parsing even if they are not
used. An optimization would be to only set up the widgets
required for currently active PCM streams. This would give
the FW the opportunity to power gate unused memory blocks,
thereby saving power.

For dynamic pipelines, the widgets in the connected DAPM path
for each PCM will need to be set up at runtime. This patch
introduces a new token, DYNAMIC_PIPELINE, for scheduler type
widgets that indicate whether a pipeline should be set up
statically during topology load or at runtime when the PCM is
opened. Introduce a new field called dynamic_pipeline_widget
in struct snd_sof_widget to save the value of the parsed token.

The token is set only for the pipeline (scheduler type)
widget and must be propagated to all widgets in the same
pipeline during topology load. Introduce another field called
pipe_widget in struct snd_sof_widget that saves the pointer to
the scheduler widget with the same pipeline ID as that of the
widget. This field is populated when the pipeline completion
callback is invoked during topology loading.

this patch allows the filters to switch to use sysclk if
ASRC's ref clks disappeared and could fix the below possible issues:
1. Avoid DA filter to keep surplus samples.
2. Avoid that AD filter works failed during dapm's power on.

For example,
if I2S clks were closed before dacdat during playback off
due to jack unplug, it causes ref clks disappeared and
DA filter remained some samples which will produce pop noise
on the next HP playback.
ASRC auto-disable could clear the samples during the playback off.

ASoC: tegra: Constify static snd_soc_ops
The struct tegra_machine_snd_ops is only assigned to the ops field in the
snd_soc_dai_link struct which is a pointer to const struct snd_soc_ops.
Make it const to allow the compiler to put it in read-only memory.

ASoC: soc-component: Remove conditional definition of debugfs data members
This simplification allows the use of the standard kernel pattern of
static inline dummy functions for debugfs code. Most systems will only
have a small number of snd_soc_components so the memory impact is
minimal.
