+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";
+ };
+};
