From: Daniel Vetter Date: Tue, 30 Apr 2013 12:01:45 +0000 (+0200) Subject: drm/i915: make SDVO TV-out work for multifunction devices X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=09ede5414f0215461c933032630bf9c3a61a8ba3;p=linux-beck.git drm/i915: make SDVO TV-out work for multifunction devices We need to track this correctly. While at it shovel the boolean to track whether the sdvo is in tv mode or not into pipe_config.
