dt-bindings: simplefb-sunxi: Add sunxi simplefb extensions 



If pre-filled framebuffer nodes are used, the firmware may need extra
properties to find the right node. This documents the properties to use
for this on sunxi platforms.

Sunxi specific Simple Framebuffer bindings



This binding documents sunxi specific extensions to the simple-framebuffer

bindings. The sunxi simplefb u-boot code relies on the devicetree containing

pre-populated simplefb nodes.



These extensions are intended so that u-boot can select the right node based

on which pipeline is being used. As such they are solely intended for

firmware / bootloader use, and the OS should ignore them.



Required properties:

- compatible: "allwinner,simple-framebuffer"

- allwinner,pipeline, one of:

  "de_be0-lcd0"

  "de_be1-lcd1"

  "de_be0-lcd0-hdmi"

  "de_be1-lcd1-hdmi"



Example:



chosen {

	#address-cells = <1>;

	#size-cells = <1>;

	ranges;



	framebuffer@0 {

		compatible = "allwinner,simple-framebuffer", "simple-framebuffer";

		allwinner,pipeline = "de_be0-lcd0-hdmi";

		clocks = <&pll5 1>, <&ahb_gates 36>, <&ahb_gates 43>,

			 <&ahb_gates 44>;

		status = "disabled";

	};

};
