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";
};
};
