From 20ff39fa4312dfaee8d1314a208e6a5a3ee51cbc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 29 Nov 2017 18:43:01 +0200 Subject: [PATCH] drm/i915: Disable DP audio for g4x MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Apparently g4x doesn't support audio over DP. Bspec lists the bit as "Reserved for Audio Output Enable", and empirical evidence tells us that the bit won't stick. So stop trying to enable DP audio on g4x.
