From dd65a6867454117ecaeb8944dc231a4737681782 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Fri, 29 Apr 2016 15:42:49 +0200 Subject: [PATCH] drm/exynos/decon5433: fix trigger configuration It seems trigger cannot be configured too early, otherwise it does not work in case of panel. The patch fixes also trigger flag logic, previously HW-TRIGGER flag was cleared in case of panel - as a result panel used always software trigger.
