+Device-Tree bindings for Samsung SoC display controller (FIMD)
+
+FIMD stands for Fully Interactive Mobile Display, is the Display Controller for
+the Samsung 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 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 : a phandle to the interrupt combiner node
+
+- interrupts : should contain a list of all FIMD IP block interrupts:
+ 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 : property defining the pinctrl configurations with a phandle
+
+- pinctrl-names : default state needs to be specified in the fimd node
+ The pinctrl bindings defined in
+ ../../../pinctrl/pinctrl-bindings.txt must be used to define a
+ pinctrl state named default.
+
+Optional Properties:
+- samsung,power-domain := a phandle to FIMD power domain node
+
+Example:
+
+SoC specific DT Entry:
+
+ fimd@11c0 {
+ compatible = samsung,exynos4210-fimd;
+ interrupt-parent = combiner;
+ reg = 0x11c0 0x2;
+ interrupt-names = fifo, vsync, lcd_sys;
+ interrupts = 11 0, 11 1, 11 2;
+ clocks = clock 140, clock 283;
+ clock-names = sclk_fimd, fimd;
+ status = disabled;
+ };
+
+Board specific DT Entry:
+
+ fimd@11c0 {
+ samsung,power-domain = pd_lcd0;
+ pinctrl-0 = lcd_sync lcd_clk lcd_en lcd0_data pwm1_out;
+ pinctrl-names = default;
+ status = okay;
+ };
