[PATCH 0/3] ASoC/pdx86/input: Introduce and use soc_intel_is_*() helpers
Hi All,
We have been open-coding x86_match_cpu() checks for enabling some SoC specific behavior in various places.
The sound/soc/intel drivers used to also open-code this but this was cleaned up a while ago introducing a number of soc_intel_is_*() helpers.
This series moves the definition of these helpers to a more public place and uses it in a couple of more places outside the sound tree.
Mark, I know we are a bit late in the cycle, but if you can pick up patch 1/3 (assuming on one objects) for 5.16, then the rest can be applied after 5.16-rc1 is out.
Regards,
Hans

The soc_intel_is_foo() helpers from sound/soc/intel/common/soc-intel-quirks.h are useful outside of the sound subsystem too.
Move these to include/linux/platform_data/x86/soc.h, so that other code can use them too.

Use the new soc_intel_is_cht() helper to find out if we are running on a CHT device rather then checking the ACPI _HRV field.
This is more reliable (some CHT devices have been found where the _HRV for the PMIC is 2 rather then 3) and leads to a nice cleanup.

P.S. Btw, since you are the maintainer of PDx86 it means either you or Mark (whoever gives an Ack to the other one) can take at least two patches that makes visible that the change is not just for a single user.

Self-nak on this. && is slightly better in case we got the first argument false. Proposed variant will always evaluate both.

Thank you all for the review and acks. I've pushed the entire series to: https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.g... now, with Andy's Reviewed-by and the acks added and Andy's nitpicks addressed.
Once the buildbot has had a chance to play with this I'll push this out to platform-drivers-x86/for-next.

Hans
