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"
