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 <[email protected]> --- drivers/video/omap2/displays/panel-taal.c | 5 +---- drivers/video/omap2/dss/dsi.c | 5 +++++ 2 files changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/video/omap2/displays/panel-taal.c b/drivers/video/omap2/displays/panel-taal.c index 4cb0449..4e888ac 100644 --- a/drivers/video/omap2/displays/panel-taal.c +++ b/drivers/video/omap2/displays/panel-taal.c @@ -1247,11 +1247,8 @@ static void taal_power_off(struct omap_dss_device *dssdev) int r; r = taal_dcs_write_0(td, DCS_DISPLAY_OFF); - if (!r) { + if (!r) r = taal_sleep_in(td); - /* HACK: wait a bit so that the message goes through */ - msleep(10); - } if (r) { dev_err(&dssdev->dev, diff --git a/drivers/video/omap2/dss/dsi.c b/drivers/video/omap2/dss/dsi.c index b6a57bb..62b11c5 100644 --- a/drivers/video/omap2/dss/dsi.c +++ b/drivers/video/omap2/dss/dsi.c @@ -4263,6 +4263,11 @@ void omapdss_dsi_display_disable(struct omap_dss_device *dssdev, mutex_lock(&dsi->lock); + dsi_sync_vc(dsidev, 0); + dsi_sync_vc(dsidev, 1); + dsi_sync_vc(dsidev, 2); + dsi_sync_vc(dsidev, 3); + dsi_display_uninit_dispc(dssdev); dsi_display_uninit_dsi(dssdev, disconnect_lanes, enter_ulps); -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
