+ 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.
For details, take a look at <file:Documentation/cpu-freq>.
