+Description: Discover CPUs in the same CPU frequency coordination domain
+
+ freqdomain_cpus is the list of CPUs (online+offline) that share
+ the same clock/freq domain (possibly at the hardware level).
+ That information may be hidden from the cpufreq core and the
+ value of related_cpus may be different from freqdomain_cpus. This
+ attribute is useful for user space DVFS controllers to get better
+ power/performance results for platforms using acpi-cpufreq.
+
+ This file is only present if the acpi-cpufreq driver is in use.
