1	Device-Tree bindings for Samsung SoC display controller (FIMD)
2	
3	FIMD (Fully Interactive Mobile Display) is the Display Controller for the
4	Samsung series of SoCs which transfers the image data from a video memory
5	buffer to an external LCD interface.
6	
7	Required properties:
8	- compatible: value should be one of the following
9			"samsung,s3c2443-fimd"; /* for S3C24XX SoCs */
10			"samsung,s3c6400-fimd"; /* for S3C64XX SoCs */
11			"samsung,s5p6440-fimd"; /* for S5P64X0 SoCs */
12			"samsung,s5pc100-fimd"; /* for S5PC100 SoC  */
13			"samsung,s5pv210-fimd"; /* for S5PV210 SoC */
14			"samsung,exynos4210-fimd"; /* for Exynos4 SoCs */
15			"samsung,exynos5250-fimd"; /* for Exynos5 SoCs */
16	
17	- reg: physical base address and length of the FIMD registers set.
18	
19	- interrupt-parent: should be the phandle of the fimd controller's
20			parent interrupt controller.
21	
22	- interrupts: should contain a list of all FIMD IP block interrupts in the
23			 order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
24			 format depends on the interrupt controller used.
25	
26	- interrupt-names: should contain the interrupt names: "fifo", "vsync",
27		"lcd_sys", in the same order as they were listed in the interrupts
28	        property.
29	
30	- pinctrl-0: pin control group to be used for this controller.
31	
32	- pinctrl-names: must contain a "default" entry.
33	
34	- clocks: must include clock specifiers corresponding to entries in the
35	         clock-names property.
36	
37	- clock-names: list of clock names sorted in the same order as the clocks
38	               property. Must contain "sclk_fimd" and "fimd".
39	
40	Optional Properties:
41	- samsung,power-domain: a phandle to FIMD power domain node.
42	
43	Example:
44	
45	SoC specific DT entry:
46	
47		fimd@11c00000 {
48			compatible = "samsung,exynos4210-fimd";
49			interrupt-parent = <&combiner>;
50			reg = <0x11c00000 0x20000>;
51			interrupt-names = "fifo", "vsync", "lcd_sys";
52			interrupts = <11 0>, <11 1>, <11 2>;
53			clocks = <&clock 140>, <&clock 283>;
54			clock-names = "sclk_fimd", "fimd";
55			samsung,power-domain = <&pd_lcd0>;
56			status = "disabled";
57		};
58	
59	Board specific DT entry:
60	
61		fimd@11c00000 {
62			pinctrl-0 = <&lcd_clk &lcd_data24 &pwm1_out>;
63			pinctrl-names = "default";
64			status = "okay";
65		};
