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";
|
|
};
