I was interested in testing these on QDF2400, an ARM64 platform, since this
series touches core ARM64 code and I'd hate to see a regression. However, I
can't figure out what baseline to use to apply these. Different patches
cause different conflicts of a variety of baselines I attempted.


Good to know that we can test DT configuration on QDF2400. I always assumed
it's ACPI only.

It is ACPI only in the production configuration. I suppose we could hack things up to do basic DT sanity, but I expect it would be nasty and non-trivial.


What are these intended to apply to?


The series alone may not get the package/socket ids correct on QDF2400.
I have not yet added support for the same as I wanted to get the initial
feedback on DT bindings. The movement of DT binding and corresponding
code should not regress and you should be able to validate only that
part.


On a cursory glance, it looks like some of the reorganized code would also be used in the ACPI path (things that are common between DT and ACPI). I do not expect problems, but I still feel its prudent to do a sanity check on actual hardware.
