From fed62e54ae1f80f4631ce154225cf019f1219e59 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 9 Aug 2012 18:13:13 +0300 Subject: [PATCH] OMAPDSS: clean up dss_mgr_set_timings dss_mgr_set_timings() can only be called when the output is not active. This means that most of the code in the function is extra, as there's no need to write the values to registers, etc, because that will be handled when the output will be enabled.
