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 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
