Subject: [PATCH 0/3] Add support for CS42L43B codec to CS42L43 driver

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
