From a4790cec3adf5eec91f397b1884706a71c70730f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 5 May 2015 17:17:35 +0300 Subject: [PATCH] drm/i915: Disable HDMI port after the pipe on PCH platforms MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit BSpec says we should disable all ports after the pipe on PCH platforms. Do so. Fixes a pipe off timeout on ILK now caused by the transcoder B workaround.
