Is it correct? It's referring to TGL thing and it's not enabled with CONFIG_SND_SOC_SOF_ALDERLAKE.

Yes that should be CONFIG_SND_SOC_SOF_TIGERLAKE.
I am starting to think as part of the Kconfig rework we might get rid of this granularity. It's not very useful to allow for a single PCI ID to be selected, and even internally we keep being confused by the platform variants.
What would be more useful is to split by IP versions, that helps identify common parts and IP-specific ones. We could have multiple PCI drivers, one per IP version, and unconditionally include all PCI IDs for that version. See e.g.
https://github.com/thesofproject/linux/pull/2683/commits/aafe349efc105f3dcba...
if we removed the #if IS_ENABLED() in that code it'd be a big simplification.
I still think it's useful at the Kconfig level to present a 'user-friendly' option, but internally we should translate to which IP version is used and add additional choices (e.g. SoundWire only starts with CNL).
Hey,

ack Takashi, 'tgl_desc' is correct but the #if guards are not correct and will result in build fail if you disable just CONFIG_SND_SOC_SOF_TIGERLAKE. In SOF CI we of course have all platforms enabled (or none), so this is not caught. I'll send a V2 tomorrow (before Pierre completes the bigger rework to sof-pci-dev).

Ack, my votes for this :)

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
