Merge branch 'samsung/soc' into next/soc2

* 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.
