Subject: [PATCH v3 0/4] ASoC: qcom: x1e80100: Correct channel mapping

Hi,

First patch is a build dependency.

Changes in v3:
- Add missing Charles' Ack
- Link to v2: https://lore.kernel.org/r/20240508-asoc-x1e80100-4-channel-mapping-v2-0-ccef9a66a572@linaro.org

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
