When the panel driver calls omapdss_dsi_display_disable() it is possible that there are still some unsent packets in the TX fifo. Add dsi_sync_vc() calls in the beginning of omapdss_dsi_display_disable() to make sure the TX fifos are empty. This allows us to remove the msleep(10) hack from panel-taal.c Signed-off-by: Tomi Valkeinen <redacted> --- drivers/video/omap2/displays/panel-taal.c | 5 +---- drivers/video/omap2/dss/dsi.c | 5 +++++ 2 files changed, 6 insertions(+), 4 deletions(-)
