SubjectRe: [PATCH v3 3/3] [RFC] CPUFreq: Add support for cpu-perf-dependencies

I am not sure how FIE will use this information, as I thought the
problem is about knowing the current frequency on a CPU instead of
which CPUs are related. Anyway, EM is good enough to get this stuff
going.

Yeah, this one. And it will be called freqdomain_cpus. Add support for
freqdomain_cpus in core, update acpi-cpufreq to reuse it instead of
adding its own and you can have it in other drivers then.
