[PATCH 0/3] ASoC: SDCA: Initial support for Cirrus Logic CS47L47

[Richard Fitzgerald]

The CS47L47 is a SDCA smart codec with UAJ (headset, jack detect) and DMIC.
This series adds the initial support for the Cirrus Logic CS47L47 codec.

The soundwire patch can be taken separately from the two ASoC patches;
there aren't any build dependencies.

  soundwire: intel_auxdevice: Add CS47L47 to wake_capable_list
  ASoC: soc_sdw_utils: Add device info for CS47L47
  ASoC: SDCA: Add CS47L47 to class driver

[PATCH 1/3] soundwire: intel_auxdevice: Add CS47L47 to wake_capable_list

[Richard Fitzgerald]

The Cirrus Logic CS47L47 codec can generate Jack events so add it to
the wake-capable list.

[PATCH 2/3] ASoC: soc_sdw_utils: Add device info for CS47L47

[Richard Fitzgerald]

Add a device info entry for the Cirrus Logic CS47L47.

CS47L47 has UAJ (headset speaker + mic + jack detect) and DMICs.
The audio ports are similar to the CS42L45 so can be based on the
CS42L45 code.

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
