OMAP: DSS2: DSI: sync when disabling a display
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 <tomi.valkeinen@ti.com>
