5config ARM_S3C2416_CPUFREQ
6	bool "S3C2416 CPU Frequency scaling support"
7	depends on CPU_S3C2416
8	help
9	  This adds the CPUFreq driver for the Samsung S3C2416 and
10	  S3C2450 SoC. The S3C2416 supports changing the rate of the
11	  armdiv clock source and also entering a so called dynamic
12	  voltage scaling mode in which it is possible to reduce the
13	  core voltage of the cpu.
14
15	  If in doubt, say N.

17config ARM_S3C2416_CPUFREQ_VCORESCALE
18	bool "Allow voltage scaling for S3C2416 arm core (EXPERIMENTAL)"
19	depends on ARM_S3C2416_CPUFREQ && REGULATOR && EXPERIMENTAL
20	help
21	  Enable CPU voltage scaling when entering the dvs mode.
22	  It uses information gathered through existing hardware and
23	  tests but not documented in any datasheet.
24
25	  If in doubt, say N.
