Sure, I'll add Documentation/ABI/testing/* entries.

However, would it be appropriate for "1. System-wide sysfs interface"
to be in "sysfs-class-power" and for "2. Device specific sysfs
interface" to be in "sysfs-devices-devfreq"?

System-wide sysfs interface is in /sys/class/power/devfreq/* and
Device specific sysfs interface is in /sys/...DEVICE.../devfreq/* .

Thank you.
