54 config ARM_EXYNOS5440_CPUFREQ
55 def_bool SOC_EXYNOS5440
56 depends on HAVE_CLK && PM_OPP && OF
58 This adds the CPUFreq driver for Samsung EXYNOS5440
59 SoC. The nature of exynos5440 clock controller is
60 different than previous exynos controllers so not using
61 the common exynos framework.
63 config ARM_HIGHBANK_CPUFREQ
64 tristate "Calxeda Highbank-based"
65 depends on ARCH_HIGHBANK
67 select GENERIC_CPUFREQ_CPU0

81 depends on REGULATOR_ANATOP
83 This adds cpufreq driver support for Freescale i.MX6Q SOC.
88 tristate "CPUfreq driver for ARM Integrator CPUs"
89 depends on ARCH_INTEGRATOR
92 This enables the CPUfreq driver for ARM Integrator CPUs.
95 config ARM_KIRKWOOD_CPUFREQ
96 def_bool ARCH_KIRKWOOD && OF
98 This adds the CPUFreq driver for Marvell Kirkwood
101 config ARM_OMAP2PLUS_CPUFREQ
103 depends on ARCH_OMAP2PLUS
104 default ARCH_OMAP2PLUS

109 depends on CPU_S3C2416
111 This adds the CPUFreq driver for the Samsung S3C2416 and
112 S3C2450 SoC. The S3C2416 supports changing the rate of the
113 armdiv clock source and also entering a so called dynamic
114 voltage scaling mode in which it is possible to reduce the
115 core voltage of the cpu.
