[PATCH v5 0/4] Add support for CS42L43B codec to CS42L43 driver

[Maciej Strozek]

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 v5:
 - use snd_soc_component_to_dapm instead of snd_soc_component_get_dapm in cs42l43_component_probe
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

[PATCH v5 1/4] ASoC: sdw_utils: Add CS42L43B codec info

[Maciej Strozek]

Add codec_info for a new variant of CS42L43. It can resue existing info
but needs a new part_id.

[PATCH v5 3/4] mfd: cs42l43: Add support for the B variant

[Maciej Strozek]

Introducing CS42L43B codec, a variant of CS42L43 which can be driven by
the same driver.

Changes in CS42L43 driver specific for CS42L43B:
- Decimator 1 and 2 are dedicated to ADC, can't be selected for PDM
- Decimators 3 and 4 are connected to PDM1
- Added Decimator 5 and 6 for PDM2
- Supports SoundWire Clock Gearing
- Updated ROM requiring no patching
- Reduced RAM space
- Each ISRC has 4 decimators now

[PATCH v5 4/4] ASoC: cs42l43: Add support for the B variant

[Maciej Strozek]

Introducing CS42L43B codec, a variant of CS42L43 which can be driven by
the same driver.

Changes in CS42L43 driver specific for CS42L43B:
- Decimator 1 and 2 are dedicated to ADC, can't be selected for PDM
- Decimators 3 and 4 are connected to PDM1
- Added Decimator 5 and 6 for PDM2
- Supports SoundWire Clock Gearing
- Updated ROM requiring no patching
- Reduced RAM space
- Each ISRC has 4 decimators now

Signed-off-by: Maciej Strozek <mstrozek@opensource.cirrus.com>
---
Changes in v5:
 - use snd_soc_component_to_dapm instead of snd_soc_component_get_dapm in cs42l43_component_probe
No changes in v3, v4

Changes in v2:
 - Adjustments to variant identification following fixes from v2 mfd patch

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
