+config ARM_S3C2416_CPUFREQ
+ bool "S3C2416 CPU Frequency scaling support"
+ depends on CPU_S3C2416
+ help
+ This adds the CPUFreq driver for the Samsung S3C2416 and
+ S3C2450 SoC. The S3C2416 supports changing the rate of the
+ armdiv clock source and also entering a so called dynamic
+ voltage scaling mode in which it is possible to reduce the
+ core voltage of the cpu.
+
+ If in doubt, say N.

+ bool "Allow voltage scaling for S3C2416 arm core (EXPERIMENTAL)"
+ depends on ARM_S3C2416_CPUFREQ && REGULATOR && EXPERIMENTAL
+ help
+ Enable CPU voltage scaling when entering the dvs mode.
+ It uses information gathered through existing hardware and
+ tests but not documented in any datasheet.
+
+ If in doubt, say N.
