Merge tag 'drm-intel-fixes-2016-05-11' of git://anongit.freedesktop.org/drm-intel into drm-fixes
Misc intel fixes, reverting MST audio which was causing oops for now. * tag 'drm-intel-fixes-2016-05-11' of git://anongit.freedesktop.org/drm-intel: drm/i915: Bail out of pipe config compute loop on LPT Revert "drm/i915: start adding dp mst audio" drm/i915/bdw: Add missing delay during L3 SQC credit programming drm/i915/lvds: separate border enable readout from panel fitter drm/i915: Update CDCLK_FREQ register on BDW after changing cdclk frequency
