Jani Nikula f30d26e468 drm/i915/eDP: do not write power sequence registers for ghost eDP ... Some machines detect an eDP port even if it's not really there, and eDP initialization has a fail path for this. Typically such machines have an LVDS display instead. A regression introduced in commit 82ed61fa1a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Oct 20 20:57:41 2012 +0200 drm/i915: make edp panel power sequence setup more robust updated the power sequence registers PCH_PP_ON_DELAYS, PCH_PP_OFF_DELAYS, and PCH_PP_DIVISOR also in the ghost eDP case, messing up the LVDS display. Split the power sequencer initialization into two, delaying the register updates until after we know the eDP is real. Note: Keep the PP_CONTROL unlocking in the first part, even if it does not update registers, per the commit message of the above mentioned commit.
