23config ARM_S3C2416_CPUFREQ
24	bool "S3C2416 CPU Frequency scaling support"
25	depends on CPU_S3C2416
26	help
27	  This adds the CPUFreq driver for the Samsung S3C2416 and
28	  S3C2450 SoC. The S3C2416 supports changing the rate of the
29	  armdiv clock source and also entering a so called dynamic
30	  voltage scaling mode in which it is possible to reduce the
31	  core voltage of the cpu.
