13 A simple frame-buffer describes a frame-buffer setup by firmware or
19 sub-nodes of the chosen node (*). Simplefb nodes must be named
20 framebuffer@<address>.
41 interaction, then the chosen node stdout-path property should point
46 It is advised that devicetree files contain pre-filled, disabled
47 framebuffer nodes, so that the firmware only needs to update the
52 If pre-filled framebuffer nodes are used, the firmware may need
