Documentation / devicetree / bindings / video / simple-framebuffer-sunxi.txt


Based on kernel version 4.3. Page generated on 2015-11-02 12:48 EST.

1	Sunxi specific Simple Framebuffer bindings
2	
3	This binding documents sunxi specific extensions to the simple-framebuffer
4	bindings. The sunxi simplefb u-boot code relies on the devicetree containing
5	pre-populated simplefb nodes.
6	
7	These extensions are intended so that u-boot can select the right node based
8	on which pipeline is being used. As such they are solely intended for
9	firmware / bootloader use, and the OS should ignore them.
10	
11	Required 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"
18	
19	Example:
20	
21	chosen {
22		#address-cells = <1>;
23		#size-cells = <1>;
24		ranges;
25	
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";
32		};
