> This time adding support for Sunrisepoint-H and Sunrisepoint-LP.
> Because of all the failed attempts by Intel to get their 10nm process
> under control, this may cover Intel Mobile CPUs marketed as 6th, 7th,
> 8th, 9th and 10th generation. So if you have a Laptop that isn't at
> least 5 years old, give this a try if pchgpio(4) doesn't attach. This
> may fix all sorts of issues with keyboards, touchpads or
> suspend/resume.

> ok?
Updated diff that masks unhandled interrupts like we do in amdgpio(4).
