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

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

[Peter Ujfalusi]

Hi,

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 1/4] PCI: pci_ids: 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).

"git log --oneline include/linux/pci_ids.h" says "pci_ids" in the

The internet (and other patches in this series) seems to think
"Novalake" is spelled "Nova Lake".

It looks like that the ASoC patch is based on the recent change that
isn't merged yet in my tree, so this series should go over ASoC tree
for now, supposedly.

Mark, could you take them (probably with minor corrections of subject
as Bjorn suggested in the thread)?

It must be the on_demand_dsp_boot support which is via ASoC tree.

I will send the updated v2 with corrections and Acks
