[PATCH v2 0/3] Add ASoC machine driver support for the RT766 and RT767 codecs.

[PATCH v2 0/3] Add ASoC machine driver support for the RT766 and RT767 codecs.

[Shuming Fan via B4 Relay]

This series adds the required codec information and codec-specific DAPM routes,
enables wake capability on Intel platforms, and avoids re-initializing blind writes.

The series includes:

Add RT766 and RT767 to the SoundWire wake-capable codec list.
Add RT766 and RT767 codec information to sdw_utils.
Add support for codec versions 3 and 4.
Add the RT766 speaker and headset DAPM routes.
Avoid re-initializing blind writes.

With these changes, the generic SoundWire machine driver can recognize the RT766/RT767
codecs and set up the corresponding ASoC DAI links and codec routes.

[PATCH v2 3/3] ASoC: rt766: avoid re-initialize the blind write

We only need to check the function_status to determine
whether the system has undergone a cold or warm reboot.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.4

Thanks!

[2/3] ASoC: sdw_utils: Add rt766/rt767 support
      https://git.kernel.org/broonie/sound/c/8eb2b0c88286
[3/3] ASoC: rt766: avoid re-initialize the blind write
      https://git.kernel.org/broonie/sound/c/be190d999369

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
