2 # ARM CPU Frequency scaling drivers
5 config ARM_S3C2416_CPUFREQ
6 bool "S3C2416 CPU Frequency scaling support"
9 This adds the CPUFreq driver for the Samsung S3C2416 and
10 S3C2450 SoC. The S3C2416 supports changing the rate of the
11 armdiv clock source and also entering a so called dynamic
12 voltage scaling mode in which it is possible to reduce the
13 core voltage of the cpu.
17 config ARM_S3C2416_CPUFREQ_VCORESCALE
18 bool "Allow voltage scaling for S3C2416 arm core (EXPERIMENTAL)"
19 depends on ARM_S3C2416_CPUFREQ && REGULATOR && EXPERIMENTAL
21 Enable CPU voltage scaling when entering the dvs mode.
22 It uses information gathered through existing hardware and
23 tests but not documented in any datasheet.
27 config ARM_S3C64XX_CPUFREQ
28 bool "Samsung S3C64XX"
29 depends on CPU_S3C6410
32 This adds the CPUFreq driver for Samsung S3C6410 SoC.
36 config ARM_S5PV210_CPUFREQ
37 bool "Samsung S5PV210 and S5PC110"
38 depends on CPU_S5PV210
41 This adds the CPUFreq driver for Samsung S5PV210 and
46 config ARM_EXYNOS_CPUFREQ
47 bool "SAMSUNG EXYNOS SoCs"
48 depends on ARCH_EXYNOS
49 select ARM_EXYNOS4210_CPUFREQ if CPU_EXYNOS4210
50 select ARM_EXYNOS4X12_CPUFREQ if (SOC_EXYNOS4212 || SOC_EXYNOS4412)
53 This adds the CPUFreq driver common part for Samsung
58 config ARM_EXYNOS4210_CPUFREQ
59 bool "Samsung EXYNOS4210"
60 depends on ARCH_EXYNOS
62 This adds the CPUFreq driver for Samsung EXYNOS4210
63 SoC (S5PV310 or S5PC210).
65 config ARM_EXYNOS4X12_CPUFREQ
66 bool "Samsung EXYNOS4X12"
68 This adds the CPUFreq driver for Samsung EXYNOS4X12
69 SoC (EXYNOS4212 or EXYNOS4412).
