topology: validator: check IPC4 pin format compatibility - #11443

Include the sample-type bits in the selector input and playback copier
input formats. These internal connections carry 32-bit LSB integer
samples, matching the DRC and crossover FIR outputs.

Leave the external SoundWire output format unchanged.

…gateways

The generic benchmark provides its own playback and capture DAI
pipelines, but also instantiates the default component-benchmark DAI
gateways. The overlapping pipeline IDs and duplicate widget names cause
the wrong format declarations and pipeline ownership to be used.

Instantiate the default gateways only with HDA_CONFIG=none. Keep the
custom gateways for HDA_CONFIG=benchmark and document the distinction.
Verify analog playback and capture at 48 kHz in S16_LE, S24_LE and
S32_LE on a TGL HDA device with kernel 7.2.14. Both directions now run
instead of playback timing out and capture failing at pipeline start.

…arks

MFCC and MFCC-mel benchmarks configure the host copiers and processing
modules for 16 kHz, but their HDA DAI copiers inherit 48 kHz formats.
F003 reports incompatible formats on both connections to the DAIs.

Use the configured HDA playback and capture rates for both sides of the
DAI copiers, and select 16 kHz for all six MFCC benchmark variants. Keep
48 kHz defaults for other component benchmarks. The copiers convert
sample formats, not sample rates, so the HDA link must also use 16 kHz.

Document the benchmark rate and feature-data output.

Verify three-second playback and capture streams at 16 kHz for each
variant in its native S16_LE, S24_LE or S32_LE format on a TGL HDA
device with kernel 7.2.14. This checks stream operation, not MFCC
algorithm correctness. Representative unaffected benchmark binaries
remain byte-identical.

The standalone SRC-gain-mixin topology declares MSB integer samples on
internal connections whose peers declare LSB integer samples. F003
reports mismatches at both the playback and capture copiers.

Use LSB integer samples for the shared playback copier input and the
standalone capture copier output. Remove their explicit fmt_cfg
overrides so the base format classes encode the selected sample type.
Keep the SoundWire-facing formats as MSB integer.

These connections carry 32 valid bits in 32-bit containers, so sample
placement is unchanged. This corrects the format declarations rather
than an observed runtime audio failure.

…cted rate

The HDA analog PCM advertises only 48 kHz in its rate list even when
its minimum and maximum rates are set to 96 kHz. The resulting empty
rate constraints prevent the stream from opening.

The playback gain, mixers and effects also retain 48 kHz defaults when
96 kHz is selected. Move the pre-mixer gain formats out of the mixer
control and configure the internal playback chain at the selected rate.
Allow the PCM rate list to include the configured rate while retaining
the fixed minimum and maximum constraints.

Keep the capture high-pass cutoff at 40 Hz for 96 kHz by using the
20 Hz / 48 kHz coefficients, which have the same normalized cutoff.

All nine 96 kHz development targets pass F003 with the validator in this
series. Playback and capture were tested on a TGL HDA device with S16_LE,
S24_LE and S32_LE at 96 kHz and with the production topology at 48 kHz.
The updated high-pass coefficients have not been tested on hardware.

The nocodec WebRTC test topology declares a 16-bit capture DAI output
feeding a copier configured for 32-bit input. Its VAD also declares
48 kHz formats while the following noise suppressor uses 16 kHz.

Configure the DAI output as 32-bit, matching the first module copier.
Make the VAD format rate selectable, defaulting to 48 kHz, and set it
to 16 kHz in this test topology. This preserves the existing sample
format and channel choices while aligning the connected formats.

The rebuilt topology passes F003. Hardware testing requires an SSP
nocodec loopback setup and has not been performed.

Resolve route endpoints to their bound input and output pins and report
an error when declared format sets have no compatible format. Do not
infer queue allocation for unbound multi-pin endpoints or constrain
undeclared secondary copier outputs. Compare mixer outputs using the
shared format set selected by the kernel for all pins.

Check sample representations independently of compatibility
normalization and reject invalid sample types and bit depths. Treat
full-width 32-bit MSB and LSB integers as equivalent, and include
container depth when evaluating declared sample types. These checks
validate declared format compatibility, not the behavior of a
particular kernel version or runtime sample alignment.

Matching declarations do not simulate runtime selection, and
module-specific configuration can require further review. Cover pin
bindings, sample types, base topologies, and siggen echo reference with
regression tests.
