How about adding status = "disabled"; above.
Sorry for not pointing it out earlier.

+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@11c00000 {
+ compatible = "samsung,exynos4210-fimd";
+ interrupt-parent = <&combiner>;
+ reg = <0x11c00000 0x20000>;
+ interrupt-names = "fifo", "vsync", "lcd_sys";
+ interrupts = <11 0>, <11 1>, <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";
+ };
