From: Thomas Abraham <redacted> The new CPU clock type allows the use of generic arm_big_little_dt cpufreq driver for Exynos5420. Changes by Bartlomiej: - split Exynos5420 support from the original patch - disable cpufreq if big.LITTLE switcher support is enabled Cc: Tomasz Figa <redacted> Cc: Kukjin Kim <redacted> Cc: Javier Martinez Canillas <redacted> Signed-off-by: Thomas Abraham <redacted> Signed-off-by: Bartlomiej Zolnierkiewicz <redacted> --- arch/arm/mach-exynos/exynos.c | 7 +++++++ 1 file changed, 7 insertions(+)
