This avoids breaking the bootloader-provided framebuffer console when simpledrm is selected to replace simplefb, as these FBs always seem to be 10-bit (at least when a real screen is attached). Changes since v1: - Moved the OF platform device setup code from simplefb into common code, instead of duplicating it in simpledrm - Rebased on drm-tip Hector Martin (3): of: Move simple-framebuffer device handling from simplefb to of drm/format-helper: Add drm_fb_xrgb8888_to_xrgb2101010_toio() drm/simpledrm: Add XRGB2101010 format drivers/gpu/drm/drm_format_helper.c | 62 +++++++++++++++++++++++++++++ drivers/gpu/drm/tiny/simpledrm.c | 2 +- drivers/of/platform.c | 5 +++ drivers/video/fbdev/simplefb.c | 21 +--------- include/drm/drm_format_helper.h | 3 ++ 5 files changed, 72 insertions(+), 21 deletions(-)
