46 config ARM_EXYNOS5440_CPUFREQ
47 def_bool SOC_EXYNOS5440
48 depends on HAVE_CLK && PM_OPP && OF
50 This adds the CPUFreq driver for Samsung EXYNOS5440
51 SoC. The nature of exynos5440 clock controller is
52 different than previous exynos controllers so not using
53 the common exynos framework.
55 config ARM_HIGHBANK_CPUFREQ
56 tristate "Calxeda Highbank-based"
57 depends on ARCH_HIGHBANK
59 select GENERIC_CPUFREQ_CPU0

70 config ARM_IMX6Q_CPUFREQ
71 tristate "Freescale i.MX6Q cpufreq support"
73 depends on REGULATOR_ANATOP
75 This adds cpufreq driver support for Freescale i.MX6Q SOC.
80 tristate "CPUfreq driver for ARM Integrator CPUs"
81 depends on ARCH_INTEGRATOR
84 This enables the CPUfreq driver for ARM Integrator CPUs.
87 config ARM_KIRKWOOD_CPUFREQ
88 def_bool ARCH_KIRKWOOD && OF
90 This adds the CPUFreq driver for Marvell Kirkwood
93 config ARM_OMAP2PLUS_CPUFREQ
95 depends on ARCH_OMAP2PLUS
96 default ARCH_OMAP2PLUS
99 config ARM_S3C2416_CPUFREQ
100 bool "S3C2416 CPU Frequency scaling support"
101 depends on CPU_S3C2416
103 This adds the CPUFreq driver for the Samsung S3C2416 and
104 S3C2450 SoC. The S3C2416 supports changing the rate of the
105 armdiv clock source and also entering a so called dynamic
106 voltage scaling mode in which it is possible to reduce the
107 core voltage of the cpu.
111 config ARM_S3C2416_CPUFREQ_VCORESCALE
112 bool "Allow voltage scaling for S3C2416 arm core"
113 depends on ARM_S3C2416_CPUFREQ && REGULATOR
115 Enable CPU voltage scaling when entering the dvs mode.
116 It uses information gathered through existing hardware and
117 tests but not documented in any datasheet.
121 config ARM_S3C64XX_CPUFREQ
122 bool "Samsung S3C64XX"
