We need this patch to fix the pre-existing bug that will make the screen become black. But, this commit based on many other changes.
commit 3739850b46f560a2be29287c3e5c29999d1a7e0e Author: Daniel Vetter <[email protected]> Date: Thu Sep 6 22:15:44 2012 +0200 drm/i915: disable the cpu edp port after the cpu pipe See bspec, Vol3 Part2, Section 1.1.3 "Display Mode Set Sequence". This applies to all platforms where we currently support eDP on, i.e. ilk, snb & ivb. Without this change we fail to light up the eDP port on previously unused crtcs (likely because something is stuck on the old pipe), and we also fail to properly disable the old pipe (i.e. bit 30 in the PIPECONF register is stuck as set until the next reboot). v2: Rebased on top of the edp panel off sequence changes in 3.6-rc2.
