2 # ARM CPU Frequency scaling drivers
5 config ARM_OMAP2PLUS_CPUFREQ
7 depends on ARCH_OMAP2PLUS
11 config ARM_S3C2416_CPUFREQ
12 bool "S3C2416 CPU Frequency scaling support"
13 depends on CPU_S3C2416
15 This adds the CPUFreq driver for the Samsung S3C2416 and
16 S3C2450 SoC. The S3C2416 supports changing the rate of the
17 armdiv clock source and also entering a so called dynamic
18 voltage scaling mode in which it is possible to reduce the
19 core voltage of the cpu.
23 config ARM_S3C2416_CPUFREQ_VCORESCALE
24 bool "Allow voltage scaling for S3C2416 arm core (EXPERIMENTAL)"
25 depends on ARM_S3C2416_CPUFREQ && REGULATOR && EXPERIMENTAL
27 Enable CPU voltage scaling when entering the dvs mode.
28 It uses information gathered through existing hardware and
29 tests but not documented in any datasheet.
33 config ARM_S3C64XX_CPUFREQ
34 bool "Samsung S3C64XX"
35 depends on CPU_S3C6410
38 This adds the CPUFreq driver for Samsung S3C6410 SoC.
42 config ARM_S5PV210_CPUFREQ
43 bool "Samsung S5PV210 and S5PC110"
44 depends on CPU_S5PV210
47 This adds the CPUFreq driver for Samsung S5PV210 and
52 config ARM_EXYNOS_CPUFREQ
53 bool "SAMSUNG EXYNOS SoCs"
54 depends on ARCH_EXYNOS
57 This adds the CPUFreq driver common part for Samsung
62 config ARM_EXYNOS4210_CPUFREQ
63 def_bool CPU_EXYNOS4210
65 This adds the CPUFreq driver for Samsung EXYNOS4210
66 SoC (S5PV310 or S5PC210).
68 config ARM_EXYNOS4X12_CPUFREQ
69 def_bool (SOC_EXYNOS4212 || SOC_EXYNOS4412)
71 This adds the CPUFreq driver for Samsung EXYNOS4X12
72 SoC (EXYNOS4212 or EXYNOS4412).
74 config ARM_EXYNOS5250_CPUFREQ
75 def_bool SOC_EXYNOS5250
77 This adds the CPUFreq driver for Samsung EXYNOS5250
80 config ARM_SPEAR_CPUFREQ
81 bool "SPEAr CPUFreq support"
85 This adds the CPUFreq driver support for SPEAr SOCs.
