1	Atmel LCDC Framebuffer
2	-----------------------------------------------------
3	
4	Required properties:
5	- compatible :
6		"atmel,at91sam9261-lcdc" , 
7		"atmel,at91sam9263-lcdc" ,
8		"atmel,at91sam9g10-lcdc" ,
9		"atmel,at91sam9g45-lcdc" ,
10		"atmel,at91sam9g45es-lcdc" ,
11		"atmel,at91sam9rl-lcdc" ,
12		"atmel,at32ap-lcdc"
13	- reg : Should contain 1 register ranges(address and length).
14		Can contain an additional register range(address and length)
15		for fixed framebuffer memory. Useful for dedicated memories.
16	- interrupts : framebuffer controller interrupt
17	- display: a phandle pointing to the display node
18	
19	Required nodes:
20	- display: a display node is required to initialize the lcd panel
21		This should be in the board dts.
22	- default-mode: a videomode within the display with timing parameters
23		as specified below.
24	
25	Optional properties:
26	- lcd-supply: Regulator for LCD supply voltage.
27	
28	Example:
29	
30		fb0: fb@0x00500000 {
31			compatible = "atmel,at91sam9g45-lcdc";
32			reg = <0x00500000 0x1000>;
33			interrupts = <23 3 0>;
34			pinctrl-names = "default";
35			pinctrl-0 = <&pinctrl_fb>;
36			display = <&display0>;
37			status = "okay";
38			#address-cells = <1>;
39			#size-cells = <1>;
40	
41		};
42	
43	Example for fixed framebuffer memory:
44	
45		fb0: fb@0x00500000 {
46			compatible = "atmel,at91sam9263-lcdc";
47			reg = <0x00700000 0x1000 0x70000000 0x200000>;
48			[...]
49		};
50	
51	Atmel LCDC Display
52	-----------------------------------------------------
53	Required properties (as per of_videomode_helper):
54	
55	 - atmel,dmacon: dma controller configuration
56	 - atmel,lcdcon2: lcd controller configuration
57	 - atmel,guard-time: lcd guard time (Delay in frame periods)
58	 - bits-per-pixel: lcd panel bit-depth.
59	
60	Optional properties (as per of_videomode_helper):
61	 - atmel,lcdcon-backlight: enable backlight
62	 - atmel,lcdcon-backlight-inverted: invert backlight PWM polarity
63	 - atmel,lcd-wiring-mode: lcd wiring mode "RGB" or "BRG"
64	 - atmel,power-control-gpio: gpio to power on or off the LCD (as many as needed)
65	
66	Example:
67		display0: display {
68			bits-per-pixel = <32>;
69			atmel,lcdcon-backlight;
70			atmel,dmacon = <0x1>;
71			atmel,lcdcon2 = <0x80008002>;
72			atmel,guard-time = <9>;
73			atmel,lcd-wiring-mode = <1>;
74	
75			display-timings {
76				native-mode = <&timing0>;
77				timing0: timing0 {
78					clock-frequency = <9000000>;
79					hactive = <480>;
80					vactive = <272>;
81					hback-porch = <1>;
82					hfront-porch = <1>;
83					vback-porch = <40>;
84					vfront-porch = <1>;
85					hsync-len = <45>;
86					vsync-len = <1>;
87				};
88			};
89		};
