Cpufreq governors?

Support for cpufreq seems to be disabled (there is no cpufreq subdirectory in /sys/devices/system/cpu/cpu0/). I noticed in the device tree there is a fixed clock frequency - does the device tree just need some additional information in order to activate cpufreq, or is there a more fundamental reason why it’s not possible on this CPU? I would very much like to measure the drop in idle power draw when using the ondemand or conservative governors.

I never looked into frequency scaling. I’m not sure if it would work or not. I’m open to looking into it, but not sure when I’ll have time.
