Merge tag 'drm-fixes-v4.7-rc1' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie: - one IMX built-in regression fix - a set of amdgpu fixes, mostly powerplay and polaris GPU stuff - a set of i915 fixes all over, many cc'ed to stable. The i915 batch contain support for DP++ dongle detection, which is used to fix some regressions in the HDMI color depth area * tag 'drm-fixes-v4.7-rc1' of git://people.freedesktop.org/~airlied/linux: (44 commits) drm/amd: add Kconfig dependency for ACP on DRM_AMDGPU drm/amdgpu: Fix hdmi deep color support. drm/amdgpu: fix bug in fence driver fini 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/imx: Match imx-ipuv3-crtc components using device node in platform data 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 ...
