  1. Sunxi specific Simple Framebuffer bindings
  2. This binding documents sunxi specific extensions to the simple-framebuffer
  3. bindings. The sunxi simplefb u-boot code relies on the devicetree containing
  4. pre-populated simplefb nodes.
  5. These extensions are intended so that u-boot can select the right node based
  6. on which pipeline is being used. As such they are solely intended for
  7. firmware / bootloader use, and the OS should ignore them.
  8. Required properties:
  9. - compatible: "allwinner,simple-framebuffer"
  10. - allwinner,pipeline, one of:
  11. "de_be0-lcd0"
  12. "de_be1-lcd1"
  13. "de_be0-lcd0-hdmi"
  14. "de_be1-lcd1-hdmi"
  15. Example:
  16. chosen {
  17. #address-cells = <1>;
  18. #size-cells = <1>;
  19. ranges;
  20. framebuffer@0 {
  21. compatible = "allwinner,simple-framebuffer", "simple-framebuffer";
  22. allwinner,pipeline = "de_be0-lcd0-hdmi";
  23. clocks = <&pll5 1>, <&ahb_gates 36>, <&ahb_gates 43>,
  24. <&ahb_gates 44>;
  25. status = "disabled";
  26. };
  27. };
