# ARM CPU Frequency scaling drivers

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.
config ARM_S3C2416_CPUFREQ_VCORESCALE
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.
config ARM_S3C64XX_CPUFREQ
bool "Samsung S3C64XX"
depends on CPU_S3C6410
default y
help
This adds the CPUFreq driver for Samsung S3C6410 SoC.
If in doubt, say N.
config ARM_S5PV210_CPUFREQ
bool "Samsung S5PV210 and S5PC110"
depends on CPU_S5PV210
default y
help
This adds the CPUFreq driver for Samsung S5PV210 and
S5PC110 SoCs.
If in doubt, say N.
config ARM_EXYNOS_CPUFREQ
bool "SAMSUNG EXYNOS SoCs"
depends on ARCH_EXYNOS
select ARM_EXYNOS4210_CPUFREQ if CPU_EXYNOS4210
default y
help
This adds the CPUFreq driver common part for Samsung
EXYNOS SoCs.
If in doubt, say N.
config ARM_EXYNOS4210_CPUFREQ
bool "Samsung EXYNOS4210"
depends on ARCH_EXYNOS
help
This adds the CPUFreq driver for Samsung EXYNOS4210
SoC (S5PV310 or S5PC210).
