| Simple Framebuffer |
| |
| A simple frame-buffer describes a raw memory region that may be rendered to, |
| with the assumption that the display hardware has already been set up to scan |
| out from that buffer. |
| |
| Required properties: |
| - compatible: "simple-framebuffer" |
| - reg: Should contain the location and size of the framebuffer memory. |
| - width: The width of the framebuffer in pixels. |
| - height: The height of the framebuffer in pixels. |
| - stride: The number of bytes in each line of the framebuffer. |
| - format: The format of the framebuffer surface. Valid values are: |
| - r5g6b5 (16-bit pixels, d[15:11]=r, d[10:5]=g, d[4:0]=b). |
| |
| Example: |
| |
| framebuffer { |
| compatible = "simple-framebuffer"; |
| reg = <0x1d385000 (1600 * 1200 * 2)>; |
| width = <1600>; |
| height = <1200>; |
| stride = <(1600 * 2)>; |
| format = "r5g6b5"; |
| }; |
