The horizontal resolution (640) for the TT High video mode (1280x960) is definitely bogus. While fixing that, correct the timings to match the TTM195 service manual. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> --- Untested on actual hardware, hence the RFC. --- drivers/video/fbdev/atafb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
