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

[Maciej Strozek <mstrozek@opensource.cirrus.com>]

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
