[PATCH 0/2] ASoC: cs35l56/57/62/63: Use the correct SoundWire DP for feedback

From: Richard Fitzgerald

Date: Mon Oct 05 2026 - 11:54:48 EST


The amp feedback path (AEC) was incorrectly using SoundWire DP3.
The firmware outputs SDCA OT25 feedback on DP4. DP3 is reserved for
SDCA companion amp.

This series adds a DAI for OT25 and switches the sdw machine driver
to use the new DAI for the feedback path.

ASoC: cs35l56: Add DAI for SDCA OT25 stream
ASoC: sdw_utils: Switch CS35L56/57/62/63 to use OT25 DAI
