From df01d53068bdf31609aafd9a857901a1f16dfa52 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 7 Mar 2012 10:28:48 +0200 Subject: [PATCH] OMAPDSS: APPLY: fix clearing shadow dirty flag with manual update Currently the shadow-dirty flags for manual update displays is cleared in the apply_irq_handler when an update has finished. This is not correct, as the shadow registers are taken into use (i.e. after that they are not dirty) when the update is started. Move the mgr_clear_shadow_dirty() call from apply_irq_handler to dss_mgr_start_update() to fix this.
