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 | |||
16 | Example: | ||
17 | |||
18 | framebuffer { | ||
19 | compatible = "simple-framebuffer"; | ||
20 | reg = <0x1d385000 (1600 * 1200 * 2)>; | ||
21 | width = <1600>; | ||
22 | height = <1200>; | ||
23 | stride = <(1600 * 2)>; | ||
24 | format = "r5g6b5"; | ||
25 | }; | ||
