Hi,
First patch is a build dependency.
Changes in v2:
- Re-work most of the idea according to Srini comments: set channel
mapping for backend DAIs, not frontend.
- Patch #1: no changes
- Patch #2 is entirely replaced - now channel mapping is implemented in
q6apm-lpass-dais.
- Patch #3: rework to new approach, but most of the code stays.
- Patch #4: rework significantly, because only backend DAIs is now
affected.
- Link to v1: https://lore.kernel.org/r/20240507-asoc-x1e80100-4-channel-mapping-v1-0-b12c13e0a55d@linaro.org
Description
===========
X1E80100 CRD is the first board, which comes with four speakers, so we
still keep fixing and adding missing pieces.
The board has speaker arranged as left front+back and then right
front+back. Using default channel mapping causes front right speaker to
play left back stream.
Adjust the channel maps for frontend DAIs to fix stereo and four-channel
playback.
Best regards,
Krzysztof

There is no need for implementations of DAI set_channel_map() to modify
contents of passed arrays with actual channel mapping. Additionally,
the caller keeps full ownership of the array.
Constify these pointer arguments so the code will be safer and easier to
read (documenting the caller's ownership).

2.43.0
The set_channel_map() implementation in q6apm-lpass-dais driver was
copying older pre-Audioreach code from q6afe-dai driver, but not really
using it. The code sets active channel mask based on passed channel
mapping, but Audioreach code does not use that mask ever. Audioreach
module configuration does have on the other hand proper channel mapping
field, which should supersed that active channel mask.
Drop the unused active channel mask and implement proper mapping of
channels in q6apm-lpass-dais driver.

Changes in v2:
1. Entirely replaced - now channel mapping is implemented in
q6apm-lpass-dais.

2.43.0
When constructing packets to DSP, the Audioreach code uses 'struct
audioreach_module_config' to configure parameters like number of
channels, bitrate, sample rate etc, but uses defaults for the channel
mapping.
Rework this code to copy the channel mapping from 'struct
audioreach_module_config', instead of using the default. This requires
all callers to fill that structure: add missing initialization of
channel mapping.
Entire patch makes code more logical and easier to follow:
1. q6apm-dai and q6apm-lpass-dais code which allocates 'struct
audioreach_module_config' initializes it fully, so fills both
the number of channels and the channel mapping.
2. Audioreach code, which uses 'struct audioreach_module_config' when
constructing packets, copies entire contents of passed config, not
only pieces of it.

Changes in v2:
1. Extend commit msg, rationale.
2. Rework to new approach, but most of the code stays.
3. Export audioreach_set_channel_mapping() (needed by Q6APM DAIS and
LPASS DAIS)
4. Correct channel mapping also in audioreach_mfc_set_media_format(),
because MFC DAI is now part of backend.
5. Do not adjust dynamic DAIs (drop audioreach_dai_load()).
