Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq
Pull cpufreq updates for 3.4 from Dave Jones: new drivers and some fixes.
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq:
provide disable_cpufreq() function to disable the API.
EXYNOS5250: Add support cpufreq for EXYNOS5250
EXYNOS4X12: Add support cpufreq for EXYNOS4X12
[CPUFREQ] CPUfreq ondemand: update sampling rate without waiting for next sampling
[CPUFREQ] Add S3C2416/S3C2450 cpufreq driver
[CPUFREQ] Fix exposure of ARM_EXYNOS4210_CPUFREQ
[CPUFREQ] EXYNOS4210: update the name of EXYNOS clock register
[CPUFREQ] EXYNOS: Initialize locking_frequency with initial frequency
[CPUFREQ] s3c64xx: Fix mis-cherry pick of VDDINT
Fix up trivial conflicts in Kconfig and Makefile due to just changes
next to each other (OMAP2PLUS changes vs some new EXYNOS cpufreq
drivers).
