+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:
+
+ fimd@11c00000 {
+ compatible = "samsung,exynos4-fimd";
+ interrupt-parent = <&combiner>;
+ reg = <0x11c00000 0x20000>;
+ interrupts = <11 1>, <11 0>, <11 2>;
+ };
+
+Board specific DT Entry:
+
+ fimd@11c00000 {
+ samsung,power-domain = <&pd_lcd0>;
+ pinctrl-0 = <&lcd_sync &lcd_clk &lcd_en &lcd0_data &pwm1_out>;
+ pinctrl-names = "default";
+ status = "okay";
+ };
