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.

* Samsung SATA PHY Controller
SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
Each SATA PHY controller should have its own node.
Required properties:

- reg : <registers mapping>
Example:
sata@ffe07000 {
compatible = "samsung,exynos5-sata-phy";

* Samsung Multi Format Codec (MFC)
Multi Format Codec (MFC) is the IP present in Samsung SoCs which
supports high resolution decoding and encoding functionalities.
The MFC device driver is a v4l2 driver which can encode/decode
video raw/elementary streams and has support for all popular
video codecs.
Required properties:
- compatible : value should be either one among the following
(a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
(b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs
- reg : Physical base address of the IP registers and length of memory
mapped region.
- interrupts : MFC interrupt number to the CPU.
- samsung,mfc-r : Base address of the first memory bank used by MFC
for DMA contiguous memory allocation and its size.
- samsung,mfc-l : Base address of the second memory bank used by MFC
for DMA contiguous memory allocation and its size.
