   1 Meson specific Simple Framebuffer bindings
   2
   3 This binding documents meson specific extensions to the simple-framebuffer
   4 bindings. The meson simplefb u-boot code relies on the devicetree containing
   5 pre-populated simplefb nodes.
   6
   7 These extensions are intended so that u-boot can select the right node based
   8 on which pipeline is being used. As such they are solely intended for
   9 firmware / bootloader use, and the OS should ignore them.

  11 Required properties:
  12 - compatible: "amlogic,simple-framebuffer", "simple-framebuffer"
  13 - amlogic,pipeline, one of:

  15   "vpu-hdmi"
