From 6dee738af60144c03cbfd0699bbb99f4ff4e021a Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 28 Mar 2014 08:54:04 +0200 Subject: [PATCH] drm/i915/tv: fix gen4 composite s-video tv-out commit e1f23f3dd817f53f622e486913ac662add46eeed upstream. This is *not* bisected, but the likely regression is commit c35614380d5c956bfda20eab2755b2f5a7d6f1e7 Author: Zhao Yakui Date: Tue Nov 24 09:48:48 2009 +0800 drm/i915: Don't set up the TV port if it isn't in the BIOS table. The commit does not check for all TV device types that might be present in the VBT, disabling TV out for the missing ones. Add composite S-video.
