14   A simple frame-buffer describes a frame-buffer setup by firmware or
20   sub-nodes of the chosen node (*). Simplefb nodes must be named
23   If the devicetree contains nodes for the display hardware used by a
24   simplefb, then the simplefb node must contain a property called
25   display, which contains a phandle pointing to the primary display
27   over control to a driver for the real hardware. The bindings for the
32   node contains a display property then the /aliases/display# path
36   If a simplefb node represents the preferred console for user
37   interaction, then the chosen node stdout-path property should point
42   It is advised that devicetree files contain pre-filled, disabled
48   If pre-filled framebuffer nodes are used, the firmware may need
