From: Maciej Strozek
Date: Fri Dec 19 2025 - 05:15:49 EST
Hello,
Introducing CS42L43B, a variant of the CS42L43 codec with changes to
PDM (DMIC) inputs, RAM/ROM memory and extra channels to two SoundWire
ports and ISRCs, and can be supported by the existing CS42L43 driver
with some modifications.
Support is split into three commits:
1. Add CS42L43B codec info to SoundWire utils
2. MFD driver part 1/2
3. ASoC codec driver part 2/2
Regards,
Maciej
