* samsung/soc:
ARM: EXYNOS: fix cycle count for periodic mode of clock event timers
ARM: EXYNOS: add support JPEG
ARM: EXYNOS: Add DMC1, allow PPMU access for DMC
ARM: SAMSUNG: Correct MIPI-CSIS io memory resource definition
ARM: SAMSUNG: fix __init attribute on regarding s3c_set_platdata()
ARM: SAMSUNG: Add __init attribute to samsung_bl_set()
ARM: S5PV210: Add usb otg phy control
ARM: S3C64XX: Add usb otg phy control
ARM: EXYNOS: Enable l2 configuration through device tree
ARM: EXYNOS: remove useless code to save/restore L2
ARM: EXYNOS: save L2 settings during bootup
ARM: S5P: add L2 early resume code
ARM: EXYNOS: Add support AFTR mode on EXYNOS4210
ARM: SAMSUNG: use spin_lock_irqsave() in clk_{enable,disable}
ARM: S3C64XX: Define some additional always off clocks
ARM: S3C64XX: Reduce residency requirement for cpuidle WFI mode
ARM: SAMSUNG: Add a callback 'notify_after' for PWM backlight control
ARM: SAMSUNG: add G2D to plat-s5p and mach-exynos
ARM: S3C64XX: Gate some more clocks by default
ARM: S3C64XX: Add basic cpuidle driver
Conflicts:
arch/arm/mach-exynos/clock.c
arch/arm/mach-exynos/common.c
This merges the earlier samsung support into the next/soc2 branch to
resolve conflicts between commits in the earlier work and the exynos5
branch.
