You missed both cpufreq maintainers and PM-list in cc :(

Haven't gone into minute details of this driver but have tried
what looks to be the way ahead.

As you also mentioned merging with cpufreq-cpu0 might be
worth and I have tried extending cpufreq-cpu0's support
for all CPUs..

It should work for Krait. I have tested it for Exynos dual-A15
and it didn't explode :)

Links aren't available yet but you can find that in your
