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	- interrupts : framebuffer controller interrupt
15	- display: a phandle pointing to the display node
16	
17	Required nodes:
18	- display: a display node is required to initialize the lcd panel
19		This should be in the board dts.
20	- default-mode: a videomode within the display with timing parameters
21		as specified below.
22	
23	Optional properties:
24	- lcd-supply: Regulator for LCD supply voltage.
25	
26	Example:
27	
28		fb0: fb@0x00500000 {
29			compatible = "atmel,at91sam9g45-lcdc";
30			reg = <0x00500000 0x1000>;
31			interrupts = <23 3 0>;
32			pinctrl-names = "default";
33			pinctrl-0 = <&pinctrl_fb>;
34			display = <&display0>;
35			status = "okay";
36			#address-cells = <1>;
37			#size-cells = <1>;
38	
39		};
40	
41	Atmel LCDC Display
42	-----------------------------------------------------
43	Required properties (as per of_videomode_helper):
44	
45	 - atmel,dmacon: dma controller configuration
46	 - atmel,lcdcon2: lcd controller configuration
47	 - atmel,guard-time: lcd guard time (Delay in frame periods)
48	 - bits-per-pixel: lcd panel bit-depth.
49	
50	Optional properties (as per of_videomode_helper):
51	 - atmel,lcdcon-backlight: enable backlight
52	 - atmel,lcdcon-backlight-inverted: invert backlight PWM polarity
53	 - atmel,lcd-wiring-mode: lcd wiring mode "RGB" or "BRG"
54	 - atmel,power-control-gpio: gpio to power on or off the LCD (as many as needed)
55	
56	Example:
57		display0: display {
58			bits-per-pixel = <32>;
59			atmel,lcdcon-backlight;
60			atmel,dmacon = <0x1>;
61			atmel,lcdcon2 = <0x80008002>;
62			atmel,guard-time = <9>;
63			atmel,lcd-wiring-mode = <1>;
64
