From f6bdddc92bbbd555868067cc529275327d1ba0fa Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Thu, 26 Oct 2017 11:14:46 +0800 Subject: [PATCH] video: add an option for video simplefb via DT 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 DE 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.
