Minor nit-picks below. The Kconfig would work but select CANNONLAKE even

Humm, I have mixed feelings here.

Yes the hardware is nearly identical, with the exception of one detail 
that's not visible to the kernel, but there is no support for DMICs with 
the Skylake driver w/ HDaudio, and Chrome platforms are only going with 
SOF, so is it wise to add these two CometLake platforms to the default 
SND_SOC_INTEL_SKYLAKE selector, which is used by a number of distributions?

I don't mind if we add those PCI IDs and people use this driver if they 
wish to, but it may be time for an explicit opt-in? The 
SND_SOC_INTEL_SKYLAKE definition should even be pruned to mean SKL, APL, 
KBL and GLK, and we can add DMI-based quirks for e.g. the Up2 board and 
GLK Chromebooks which work with SOF.

You mean SND_SOC_SOF_HDA_COMMON I assume.
Except that I also need &cnl_desc, so I need CANNONLAKE to be on as
well. Should I select them both?

I don't have the context here, so feel free to ignore me. But it seems
like such a tiny amount of extra bits to add to make Cometlake work,
and then there's no hassle for the distributions when Cometlake
devices start showing up in the wild. So while things are more or less
the same, why not continue piggypacking off the default?
Or are you saying that the lack of DMIC support means the default
should be to use a different driver?

Ah I see. I'd rather use a different descriptor then, and make the two 
platforms independent, as I did for CoffeeLake. You can use the same 
descriptor for the two -H and -LP skews though.

Yes, it's the latter case, SOF will be the only driver supporting DMICs 
on CometLake, so it'd be better to avoid creating a conflict with SOF or 
enabling a configuration by default which is known to have restrictions. 
It's fine to add the CML IDs, but better avoid adding CML under the 
SKYLAKE all-you-can-eat selector.

Ok, I'll plan to remove the new selects from under SND_SOC_INTEL_SKYLAKE.
