In linux kernel since version 2.6.12  
This adds the cpufreq driver for SuperH. Any CPU that supports
clock rate rounding through the clock framework can use this
driver. While it will make the kernel slightly larger, this is
harmless for CPUs that don't support rate rounding. The driver
will also generate a notice in the boot log before disabling
itself if the CPU in question is not capable of rate rounding.

If unsure, say N.
