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"
|
"mixer0-lcd0"
|
"mixer0-lcd0-hdmi"
|
"mixer1-lcd1-hdmi"
|
"mixer1-lcd1-tve"
|
|
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>;
|
};
|
};
