Subject: [PATCH] Revert "drm/i915: Allow LVDS on pipe A on gen4+"
Date: Tue,  7 Sep 2010 23:45:45 +0100	[thread overview]
Message-ID: <1283899545-18774-1-git-send-email-chris@chris-wilson.co.uk> (raw)

This reverts commit 0f3ee801b332d6ff22285386675fe5aaedf035c3.

Enabling LVDS on pipe A was causing excessive wakeups on otherwise idle
system due to i915 interrupts. So restrict the LVDS to pipe B once more,
whilst the issue is properly diagnosed.
