+Device-Tree bindings for Samsung SoC display controller (FIMD)
+
+FIMD (Fully Interactive Mobile Display) is the Display Controller for the
+Samsung series of SoCs which transfers the image data from a video memory buffer
+to an external LCD interface.
+
+Required properties:
+- compatible: value should be one of the following
+ "samsung,s3c2443-fimd"; /* for S3C24XX SoCs */
+ "samsung,s3c6400-fimd"; /* for S3C64XX SoCs */
+ "samsung,s5p6440-fimd"; /* for S5P64X0 SoCs */
+ "samsung,s5pc100-fimd"; /* for S5PC100 SoC */
+ "samsung,s5pv210-fimd"; /* for S5PV210 SoC */
+ "samsung,exynos4210-fimd"; /* for Exynos4 SoCs */
+ "samsung,exynos5250-fimd"; /* for Exynos5 SoCs */
+
+- reg: physical base address of the FIMD and length of memory mapped region
+
+- interrupt-parent: should be the phandle of the fimd controller's
+ parent interrupt controller.
+
+- interrupts: should contain a list of all FIMD IP block interrupts in the
+ order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
+ format depends on the interrupt controller used.
+
+- interrupt-names: should contain the interrupt names: "fifo", "vsync",
+ "lcd_sys", in the same order as they were listed in the interrupts
+ property.
+
+- pinctrl-0: pin control group to be used for this controller.
+
+- pinctrl-names: must contain a "default" entry.
+
+- clocks: must include clock specifiers corresponding to entries in the
+ clock-names properties.
+
+- clock-names: List of clock names sorted in the same order as the clocks
+ property. Must contain "sclk_fimd" and "fimd".
+
+Optional Properties:
+- samsung,power-domain: a phandle to FIMD power domain node
+
+Example:
+
+SoC specific DT entry:
+
+ fimd@11c00000 {
+ compatible = "samsung,exynos4210-fimd";
+ interrupt-parent = <&combiner>;
+ reg = <0x11c00000 0x20000>;
+ interrupt-names = "fifo", "vsync", "lcd_sys";
+ interrupts = <11 0>, <11 1>, <11 2>;
+ clocks = <&clock 140>, <&clock 283>;
+ clock-names = "sclk_fimd", "fimd";
+ samsung,power-domain = <&pd_lcd0>;
+ status = "disabled";
+ };
+
+Board specific DT entry:
+
+ fimd@11c00000 {
+ pinctrl-0 = <&lcd_clk &lcd_data24 &pwm1_out>;
+ pinctrl-names = "default";
+ status = "okay";
+ };
