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";
};
