# # ARM CPU Frequency scaling drivers # config ARM_BIG_LITTLE_CPUFREQ tristate "Generic ARM big LITTLE CPUfreq driver" depends on ARM_CPU_TOPOLOGY && PM_OPP && HAVE_CLK help This enables the Generic CPUfreq driver for ARM big.LITTLE platforms. config ARM_DT_BL_CPUFREQ tristate "Generic probing via DT for ARM big LITTLE CPUfreq driver" depends on ARM_BIG_LITTLE_CPUFREQ && OF help This enables probing via DT for Generic CPUfreq driver for ARM big.LITTLE platform. This gets frequency tables from DT. 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_EXYNOS5440_CPUFREQ def_bool SOC_EXYNOS5440 depends on HAVE_CLK && PM_OPP && OF help This adds the CPUFreq driver for Samsung EXYNOS5440 SoC. The nature of exynos5440 clock controller is different than previous exynos controllers so not using the common exynos framework. config ARM_HIGHBANK_CPUFREQ tristate "Calxeda Highbank-based" depends on ARCH_HIGHBANK select CPU_FREQ_TABLE select GENERIC_CPUFREQ_CPU0 select PM_OPP select REGULATOR default m help This adds the CPUFreq driver for Calxeda Highbank SoC based boards. If in doubt, say N. config ARM_IMX6Q_CPUFREQ tristate "Freescale i.MX6Q cpufreq support" depends on SOC_IMX6Q depends on REGULATOR_ANATOP help This adds cpufreq driver support for Freescale i.MX6Q SOC. If in doubt, say N. config ARM_INTEGRATOR tristate "CPUfreq driver for ARM Integrator CPUs" depends on ARCH_INTEGRATOR default y help This enables the CPUfreq driver for ARM Integrator CPUs. If in doubt, say Y. config ARM_KIRKWOOD_CPUFREQ def_bool ARCH_KIRKWOOD && OF help This adds the CPUFreq driver for Marvell Kirkwood SoCs. 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" depends on ARM_S3C2416_CPUFREQ && REGULATOR 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 select CPU_FREQ_TABLE default y help This adds the CPUFreq driver for Samsung S5PV210 and S5PC110 SoCs. If in doubt, say N. config ARM_SA1100_CPUFREQ bool config ARM_SA1110_CPUFREQ bool config ARM_SPEAR_CPUFREQ bool "SPEAr CPUFreq support" depends on PLAT_SPEAR default y help This adds the CPUFreq driver support for SPEAr SOCs.
