[PATCH v1 2/2] ASoC: Intel: Skylake: Add Cometlake PCI IDs

[Evan Green]

Add PCI IDs for Intel CometLake platforms, which from a software
point of view are extremely similar to Cannonlake platforms.

This is odd. I checked internally a few weeks back and the CML PCI ID 
was 9dc8, same as WHL and CNL, so we did not add a PCI ID on purpose. To 
the best of my knowledge SOF probes fine on CML and the known issues can 
be found on the SOF github [1].

Care to send the log of sudo lspci -s 0:1f.3 -vn ?

The PCI ID change is seen on later production Si versions. The PCI ID is 02c8.

we must be talking about a different skew. I'll check, give me a couple

As I suspected, we are talking about different skews and generations of 
the chipset and a board-level change, not silicon change.

The CNL PCH-LP PCI ID is 0x9DC8, the CNL PCH-H PCI ID is 0xA348 (used 
for CoffeeLake). Both are supported by SOF.

What we are missing are the PCI IDs for CML PCH-LP (0x02C8) and CML 
PCH-H (0x06C8).

Can we respin this patchset to add support for those last two instead of 
just the -LP case?

I'll send a patch to add those IDs for the HDaudio legacy driver for 
consistency.

Thanks!

Sure. So just to clarify, you want the entry for 0x02c8, and you want
an additional entry for 0x06c8 under the same config. Will do.

Actually I've got that change ready to go too, I'm happy to send that out.

I'd like both entries but with different Kconfigs (e.g. CometLake-LP and 
CometLake-H). We have one PCI ID per Kconfig so far.

I guess I beat you to it.
Thanks for reporting all this.
