[PATCH v3 0/5] Add DRM FIMD DT support for Exynos4 DT Machines

[PATCH v3 0/5] Add DRM FIMD DT support for Exynos4 DT Machines

[Vikas Sajjan]

This patch series adds support for DRM FIMD DT for Exynos4 DT Machines,
specifically for Exynos4412 SoC.

changes since v2:
	- added alias to 'fimd@11c00000' node
		(reported by: Rahul Sharma <r.sh.open@gmail.com>)
	- removed 'lcd0_data' node as there was already a similar node lcd_data24
		(reported by: Jingoo Han <jg1.han@samsung.com>
	- replaced spaces with tabs in display-timing node

changes since v1:
	- added new patch to add FIMD DT binding Documentation
	- removed patch enabling SAMSUNG_DEV_BACKLIGHT and SAMSUNG_DEV_PMW 
	for mach-exynos4 DT
	- added 'status' property to fimd DT node

Is based on branch "for-next"

+Device-Tree bindings for fimd driver
+
+FIMD stands for Fully Interactive Mobile Display, is the Display Controller for
+the Exynos series of SoCs which transfers the image data from a video buffer
+located in the system memory to an external LCD interface.
+
+Required properties:
+- compatible := value should be "samsung,exynos5-fimd" or "samsung,exynos4-fimd"
+- reg := physical base address of the fimd and length of memory mapped region
+- interrupt-parent := reference to the interrupt combiner node with phandle
+- interrupts := interrupt number from the combiner to the cpu
+- pinctrl := property defining the pinctrl configurations with a phandle
+- pinctrl-names := name of the pinctrl
+
+Optional Properties:
+- samsung,power-domain := power domain property defined with a phandle
+- status := property defining the status of the node
+
+Example:
+
+SoC specific DT Entry:
