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	Example:
24	
25		fb0: fb@0x00500000 {
26			compatible = "atmel,at91sam9g45-lcdc";
27			reg = <0x00500000 0x1000>;
28			interrupts = <23 3 0>;
29			pinctrl-names = "default";
30			pinctrl-0 = <&pinctrl_fb>;
31			display = <&display0>;
32			status = "okay";
33			#address-cells = <1>;
34			#size-cells = <1>;
35	
36		};
37	
38	Atmel LCDC Display
39	-----------------------------------------------------
40	Required properties (as per of_videomode_helper):
41	
42	 - atmel,dmacon: dma controler configuration
43	 - atmel,lcdcon2: lcd controler configuration
44	 - atmel,guard-time: lcd guard time (Delay in frame periods)
45	 - bits-per-pixel: lcd panel bit-depth.
46	
47	Optional properties (as per of_videomode_helper):
48	 - atmel,lcdcon-backlight: enable backlight
49	 - atmel,lcd-wiring-mode: lcd wiring mode "RGB" or "BRG"
50	 - atmel,power-control-gpio: gpio to power on or off the LCD (as many as needed)
51	
52	Example:
53		display0: display {
54			bits-per-pixel = <32>;
55			atmel,lcdcon-backlight;
56			atmel,dmacon = <0x1>;
57			atmel,lcdcon2 = <0x80008002>;
58			atmel,guard-time = <9>;
59			atmel,lcd-wiring-mode = <1>;
60	
61			display-timings {
62				native-mode = <&timing0>;
63				timing0: timing0 {
64					clock-frequency = <9000000>;
65					hactive = <480>;
66					vactive = <272>;
