8482c81c77 ARM: EXYNOS: use 'exynos4-sdhci' as device name for sdhci controllers
With the addition of platform specific driver data in the sdhci driver
for EXYNOS4 and EXYNOS5, the device name of sdhci controllers on EXYNOS4
and EXYNOS5 are changed accordingly.

bca10b906f ARM: EXYNOS: Change System MMU platform device definitions
Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.

This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.

This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

853a0231e0 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.

7902546652 ARM: EXYNOS: Add clkdev lookup entry for lcd clock
The framebuffer driver needs the clock named 'lcd' as its bus
clock but the equivalent clock on Exynos4 is named as 'fimd'.
Hence, create a clkdev lookup entry with the name 'lcd' that
references the 'fimd' clock.

8f7b13218b ARM: EXYNOS: Add apb_pclk clkdev entry for mdma1
Amba core assumes the pclk to be named as apb_pclk. During device probe,
it tries to get that clock and enable that. When PM_RUNTIME is enabled,
dma clock is not explicitly enabled in pl330_probe, which causes device
probe to fail. Adding a clkdev entry for apb_pclk for mdma1 fixes the
problem.

This patch fixes following runtime error.

dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.2 failed with error -22

ce9c00eea1 ARM: EXYNOS: replace clock.c for other new EXYNOS SoCs
This patch changes the name of clock.c to clock-exynos4.c for other
EXYNOS series such as EXYNOS5. And since the header file of clock
is used only in arch/arm/mach-exynos, moves it in the local directory.
