[0/4] ASoC: SOF: Intel: improve and extend HDaudio-based wakes

Message

Pierre-Louis Bossart April 4, 2024, 7:03 p.m. UTC

For LunarLake, the SoundWire in-band wake detection is reported with
the HDAudio WAKE_EN/WAKE_STS registers. In the existing code, these
registers are only handled for HDaudio codecs. Now the same registers
have to be handled with care as shared resources.

The in-band wake detection mainly used for jack detection. Without
this patchset, the SoundWire headset codecs signal an event that would
be ignored and not reported.

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
