Merge branch 'next/soc-exynos5440' of... 

Merge branch 'next/soc-exynos5440' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/soc

From Kukjin Kim:
This is adding support for exynos5440, including Quad ARM Cortex-A15
cores and its reference board SSDK5440.

Note, at this moment, just enabled minimal system part for initial kernel
boot and pinctrl driver.

* 'next/soc-exynos5440' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung

:
  ARM: dts: Add pin controller node for Samsung EXYNOS5440 SoC
  pinctrl: exynos5440: add pinctrl driver for Samsung EXYNOS5440 SoC
  ARM: dts: add initial dts file for EXYNOS5440, SSDK5440
  ARM: EXYNOS: add support for EXYNOS5440 SoC

Add/add conflict in arch/arm/boot/dts/Makefile.
