1	Simple Framebuffer
2	
3	A simple frame-buffer describes a raw memory region that may be rendered to,
4	with the assumption that the display hardware has already been set up to scan
5	out from that buffer.
6	
7	Required properties:
8	- compatible: "simple-framebuffer"
9	- reg: Should contain the location and size of the framebuffer memory.
10	- width: The width of the framebuffer in pixels.
11	- height: The height of the framebuffer in pixels.
12	- stride: The number of bytes in each line of the framebuffer.
13	- format: The format of the framebuffer surface. Valid values are:
14	  - r5g6b5 (16-bit pixels, d[15:11]=r, d[10:5]=g, d[4:0]=b).
15	  - a8b8g8r8 (32-bit pixels, d[31:24]=a, d[23:16]=b, d[15:8]=g, d[7:0]=r).
16	
17	Example:
18	
19		framebuffer {
20			compatible = "simple-framebuffer";
21			reg = <0x1d385000 (1600 * 1200 * 2)>;
22			width = <1600>;
23			height = <1200>;
24			stride = <(1600 * 2)>;
25			format = "r5g6b5";
26		};
