I guess snd_soc_acpi_intel_tgl_* would be missing even by this patch
alone if TIGERLAKE=n and ALDERLAKE=y.

IMO, the easiest fix would be to select CONFIG_SND_SOC_SOF_TIGERLAKE
from CONFIG_SND_SOC_SOF_ALDERLAKE forcibly in Kconfig instead.  Then
no tweak of ifdef is needed.


thanks,

Takashi

The ACPI matching tables soc-acpi-intel-match.h are not behind Kconfig 
ifdefs, so this is ok. I did actually test all the build combinations this 
time :) and the builds go through.

I'd rather keep this here. We may later update sof_dev_desc for ADL and no 
longer reuse tgl_desc, and then it's easier to cleanup if the #ifdef is 
only here, close to where the dependency is.

I too think the ifdefs are too finegrained, so maybe the next step is to 
just drop these, and/or reduce their number. We can review and discuss 
this when we refactor sof-pci-dev to address the concern Arnd raised.

Br, Kai

Fair enough.  Thanks.

Applied to

Thanks!

[1/1] ASoC: SOF: Intel: initial support to AlderLake-P
      commit: 39860fe070c97e62ae9e80addce40ce0b3c2b082

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
