There is still a gap between vanilla v4.14 version of the driver and
the upstream commits that allow to use it with ACPI (although much
smaller than for v4.11). What is a procedure of providing you the
patches?

Is v4.14-based Centos an official version to support aarch64? If yes,
I'd complement this version with the needed patches.

Btw. if I google 'Centos aarch64' the links point to the altarch/7
images. What is their kernel base then? In other words, where should
one search
for most recent image of aarch64 images? Is there any public release
schedule available?

About sig-altarch tree, I'd need to make sure internally. From your
perspective, would it be recommended?

For sure I need to send updated patch list for v4.14. Please see my
question above.

Thanks,
