The datasheet suggests 60 for tHFP, so let's adjust the number accordingly. This also makes the framerate be 60Hz as intended: 159916.0 * 1000 / ((1200 + 80 + 24 + 60)*(1920 + 20 + 4 + 10)) => 60.00 Hz Signed-off-by: Nicolas Boichat <drinkcat@chromium.org> --- This also matches the values that we use in our chromeos-4.19 vendor kernel. Applies on top or drm-misc/drm-misc-next. drivers/gpu/drm/panel/panel-boe-tv101wum-nl6.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
