[PATCH v4 0/4] Add support for CS42L43B codec to CS42L43 driver

Posted by Maciej Strozek 1 week, 5 days ago

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 four commits:
 1. Add CS42L43B codec info to SoundWire utils
 2. Add dt binding for the new variant
 3. MFD driver part 1/2
 4. ASoC codec driver part 2/2

Regards,
Maciej

---
Changes in v4:
 - change variant_id to long int
Changes in v3:
 - fix incorrect type cast in mfd patch
Changes in v2:
 - Rework the mechanism to identify the new variant along with some
   error handling improvements.
 - Added some comments in cs42l43_readable_register() for clarity.
 - Add handling of the I2C path for the B variant
 - Add a dt binding for the new variant
