Merge tag 'drm-intel-next-fixes-2016-05-25' of git://anongit.freedesktop.org/drm-intel into drm-next
I see the main drm pull got merged, here's the first batch of fixes for 4.7 already. Fixes all around, a large portion cc: stable stuff. [airlied: the DP++ stuff is a regression fix]. * tag 'drm-intel-next-fixes-2016-05-25' of git://anongit.freedesktop.org/drm-intel: drm/i915: Stop automatically retiring requests after a GPU hang drm/i915: Unify intel_ring_begin() drm/i915: Ignore stale wm register values on resume on ilk-bdw (v2) drm/i915/psr: Try to program link training times correctly drm/i915/bxt: Adjusting the error in horizontal timings retrieval drm/i915: Don't leave old junk in ilk active watermarks on readout drm/i915: s/DPPL/DPLL/ for SKL DPLLs drm/i915: Fix gen8 semaphores id for legacy mode drm/i915: Set crtc_state->lane_count for HDMI drm/i915/BXT: Retrieving the horizontal timing for DSI drm/i915: Protect gen7 irq_seqno_barrier with uncore lock drm/i915: Re-enable GGTT earlier during resume on pre-gen6 platforms drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT drm/i915: Enable/disable TMDS output buffers in DP++ adaptor as needed drm/i915: Respect DP++ adaptor TMDS clock limit drm: Add helper for DP++ adaptors
