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.
