Add support for Intel Comet Lake platforms by adding a new Kconfig for
CometLake and the appropriate PCI ID.
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].
The PCI ID change is seen on later production Si versions. The PCI ID is 02c8.
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!
