Add an option to indicate that the video driver should setup a SimpleFB node that passes the video framebuffer initialized by U-Boot to the operating system kernel. Currently only the Allwinner DE1 driver uses this option, and the definition of this option in the sunxi-common.h config header is converted to an imply of this option from CONFIG_VIDEO_SUNXI. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> --- Changes in v5: - Convert Allwinner DE1 to use the option. Changes in v4: - Remove the dependency of VIDEO_DT_SIMPLEFB. arch/arm/mach-sunxi/Kconfig | 1 + drivers/video/Kconfig | 8 ++++++++ include/configs/sunxi-common.h | 3 --- 3 files changed, 9 insertions(+), 3 deletions(-)
