1Sunxi specific Simple Framebuffer bindings
2
3This binding documents sunxi specific extensions to the simple-framebuffer
4bindings. The sunxi simplefb u-boot code relies on the devicetree containing
5pre-populated simplefb nodes.
6
7These extensions are intended so that u-boot can select the right node based
8on which pipeline is being used. As such they are solely intended for
9firmware / bootloader use, and the OS should ignore them.

11Required properties:
12- compatible: "allwinner,simple-framebuffer"
13- allwinner,pipeline, one of:
14  "de_be0-lcd0"
15  "de_be1-lcd1"
16  "de_be0-lcd0-hdmi"
17  "de_be1-lcd1-hdmi"

22	#address-cells = <1>;
23	#size-cells = <1>;
24	ranges;

26	framebuffer@0 {
27		compatible = "allwinner,simple-framebuffer", "simple-framebuffer";
28		allwinner,pipeline = "de_be0-lcd0-hdmi";
29		clocks = <&pll5 1>, <&ahb_gates 36>, <&ahb_gates 43>,
30			 <&ahb_gates 44>;
31		status = "disabled";
