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; | |

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>, | |
