# # ARM CPU Frequency scaling drivers # config ARM_OMAP2PLUS_CPUFREQ bool "TI OMAP2+" depends on ARCH_OMAP2PLUS default ARCH_OMAP2PLUS select CPU_FREQ_TABLE 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 default y help This adds the CPUFreq driver common part for Samsung EXYNOS SoCs. If in doubt, say N. config ARM_EXYNOS4210_CPUFREQ def_bool CPU_EXYNOS4210 help This adds the CPUFreq driver for Samsung EXYNOS4210 SoC (S5PV310 or S5PC210). config ARM_EXYNOS4X12_CPUFREQ def_bool (SOC_EXYNOS4212 || SOC_EXYNOS4412) help This adds the CPUFreq driver for Samsung EXYNOS4X12 SoC (EXYNOS4212 or EXYNOS4412). config ARM_EXYNOS5250_CPUFREQ def_bool SOC_EXYNOS5250 help This adds the CPUFreq driver for Samsung EXYNOS5250 SoC. config ARM_SPEAR_CPUFREQ bool "SPEAr CPUFreq support" depends on PLAT_SPEAR default y help This adds the CPUFreq driver support for SPEAr SOCs.
