General informations

The Linux kernel configuration item CONFIG_SH_CPU_FREQ has multiple definitions:

SuperH CPU Frequency driver found in arch/sh/Kconfig

The configuration item CONFIG_SH_CPU_FREQ:

Help text

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 Documentation/cpu-freq.

If unsure, say N.
