From 1612c8bd4cef20dd06e8622bb8ab9bbe9f90c0e5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 5 May 2015 17:17:34 +0300 Subject: [PATCH] drm/i915: Fix the IBX transcoder B workarounds MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently the IBX transcoder B workarounds are not working correctly. Well, the HDMI one seems to be working somewhat, but the DP one is definitely busted. After a bit of experimentation it looks like the best way to make this work is first disable the port on transcoder B, and then re-enable it transcoder A, and immediately disable it again. We can also clean up the code by noting that we can't be called without a valid crtc. And also note that port A on ILK does not need the workaround, so let's check for that one too.
