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).
