2 # ARM CPU Frequency scaling drivers
5 config ARM_BIG_LITTLE_CPUFREQ
7 depends on ARM_CPU_TOPOLOGY
9 config ARM_DT_BL_CPUFREQ
10 tristate "Generic ARM big LITTLE CPUfreq driver probed via DT"
11 select ARM_BIG_LITTLE_CPUFREQ
12 depends on OF && HAVE_CLK
14 This enables the Generic CPUfreq driver for ARM big.LITTLE platform.
15 This gets frequency tables from DT.
17 config ARM_OMAP2PLUS_CPUFREQ
19 depends on ARCH_OMAP2PLUS
20 default ARCH_OMAP2PLUS
23 config ARM_S3C2416_CPUFREQ
24 bool "S3C2416 CPU Frequency scaling support"
25 depends on CPU_S3C2416
27 This adds the CPUFreq driver for the Samsung S3C2416 and
28 S3C2450 SoC. The S3C2416 supports changing the rate of the
29 armdiv clock source and also entering a so called dynamic
30 voltage scaling mode in which it is possible to reduce the
31 core voltage of the cpu.
35 config ARM_S3C2416_CPUFREQ_VCORESCALE
36 bool "Allow voltage scaling for S3C2416 arm core"
37 depends on ARM_S3C2416_CPUFREQ && REGULATOR
39 Enable CPU voltage scaling when entering the dvs mode.
40 It uses information gathered through existing hardware and
41 tests but not documented in any datasheet.
