From: Francisco Jerez Date: Tue, 20 Jul 2010 14:48:08 +0000 (+0200) Subject: drm/nv17-nv4x: Attempt to init some external TMDS transmitters. X-Git-Tag: v2.6.36-rc3~9^2~7^2~29 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a9f822fe1a6ca5de7d8cdd5efbead3b9ab4283b;p=platform%2Fkernel%2Flinux-3.10.git drm/nv17-nv4x: Attempt to init some external TMDS transmitters. sil164 and friends are the most common, usually they just need to be poked once because a fixed configuration is enough for any modes and clocks, so they worked without this patch if the BIOS had done a good job on POST. Display couldn't survive a suspend/resume cycle though. Unfortunately, BIOS scripts are useless here.
