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