From 0b3d9cfe7d6ac9cedd2ddbb6f3415980b3cfc36e Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 22 Aug 2012 11:33:32 +0300 Subject: [PATCH] OMAPDSS: HDMI: fix initial HDMI enable Commit 7849398fa28c21dad24292b838b059a862f99f16 introduced a bug, causing the following error to be reported: [ 370.827819] cannot lock PLL [ 370.830749] CFG1 0x1e [ 370.833160] CFG2 0x602004 [ 370.835876] CFG4 0x40000 [ 370.838562] omapdss HDMI: Failed to lock PLL However, HDMI output is still enabled. The problem is that we enable the HDMI video output temporarily when reading EDID or detecting if a HDMI cable is connected (ugh), and the commit above changes the behavior of the driver so that the video timings are not yet configured at the point when EDID is read. This patch fixes the problem by configuring the initial VGA timings at HDMI probe.
