1Sunxi specific Simple Framebuffer bindings 2 3This binding documents sunxi specific extensions to the simple-framebuffer 4bindings. The sunxi simplefb u-boot code relies on the devicetree containing 5pre-populated simplefb nodes. 6 7These extensions are intended so that u-boot can select the right node based 8on which pipeline is being used. As such they are solely intended for 9firmware / bootloader use, and the OS should ignore them. 10 11Required 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 19Example: 20 21chosen { 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 }; 33}; 34
