Merge branch 'next/dt-samsung' of...

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

From Kukjin Kim:

Here is Samsung DT for v3.8 and this is including DT for EXYNOS4X12
SoC, SMDK4412 board, pinctrl for exynos4x12, TMU, MFC, SATA and SATA
PHY.

As I commented on [4/7], this branch merged pinctrl/samsung to support
pinctrl for exynos4x12 without useless merge conflicts.
