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 }; 26
