   1Simple Framebuffer
   2
   3A simple frame-buffer describes a raw memory region that may be rendered to,
   4with the assumption that the display hardware has already been set up to scan
   5out from that buffer.
   6
   7Required 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).

  16Example:
  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        };
