[PATCH v2 0/4] ASoC/SOF/PCI/Intel: Support for Nova Lake

[Peter Ujfalusi]

Hi,

Changes since v1:
- commit message/subject fixes suggested by Bjorn
- Acked-by tags added.

this series adds audio support for the NVL variant of the
Nova Lake family.
NVL also based on ACE4 audio subsystem, but with higher clock
rate, more DSP memory and more DSP cores (4 vs 2) compared to
NVL-S.

Regards,
Peter

[PATCH v2 1/4] PCI: Add Intel Nova Lake audio Device ID

[Peter Ujfalusi]

Add Nova Lake (NVL) audio Device ID

The ID will be used by HDA legacy, SOF audio stack and the driver
to determine which audio stack should be used (intel-dsp-config).

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
