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

69 config ARM_IMX6Q_CPUFREQ
70 tristate "Freescale i.MX6Q cpufreq support"
72 depends on REGULATOR_ANATOP
74 This adds cpufreq driver support for Freescale i.MX6Q SOC.
79 tristate "CPUfreq driver for ARM Integrator CPUs"
80 depends on ARCH_INTEGRATOR
83 This enables the CPUfreq driver for ARM Integrator CPUs.
86 config ARM_KIRKWOOD_CPUFREQ
87 def_bool ARCH_KIRKWOOD && OF
89 This adds the CPUFreq driver for Marvell Kirkwood
92 config ARM_OMAP2PLUS_CPUFREQ
94 depends on ARCH_OMAP2PLUS
95 default ARCH_OMAP2PLUS
98 config ARM_S3C2416_CPUFREQ
99 bool "S3C2416 CPU Frequency scaling support"
100 depends on CPU_S3C2416
102 This adds the CPUFreq driver for the Samsung S3C2416 and
103 S3C2450 SoC. The S3C2416 supports changing the rate of the
104 armdiv clock source and also entering a so called dynamic
105 voltage scaling mode in which it is possible to reduce the
106 core voltage of the cpu.
110 config ARM_S3C2416_CPUFREQ_VCORESCALE
111 bool "Allow voltage scaling for S3C2416 arm core"
112 depends on ARM_S3C2416_CPUFREQ && REGULATOR
114 Enable CPU voltage scaling when entering the dvs mode.
115 It uses information gathered through existing hardware and
116 tests but not documented in any datasheet.
