This time really the last i915 batch for v4.15: - PSR state tracking in crtc state (Ville) - Fix eviction when the GGTT is idle but full (Chris) - BDW DP aux channel timeout fix (James) - LSPCON detection fixes (Shashank) - Use for_each_pipe to iterate over pipes (Mika Kahola) - Replace *_reference/unreference() or *_ref/unref with _get/put() (Harsha) - Refactoring and preparation for DDI encoder type cleanup (Ville) - Broadwell DDI FDI buf translation fix (Chris) - Read CSB and CSB write pointer from HWSP in GVT-g VM if available (Weinan) - GuC/HuC firmware loader refactoring (Michal) - Make shrinking more effective and not stall so much (Chris) - Cannonlake PLL fixes (Rodrigo) - DP MST connector error propagation fixes (James) - Convert timers to use timer_setup (Kees Cook) - Skylake plane enable/disable unification (Juha-Pekka) - Fix to actually free driver internal objects when requested (Chris) - DDI buf trans refactoring (Ville) - Skip waking the device to service pwrite (Chris) - Improve DSI VBT backlight parsing abstraction (Madhav) - Cannonlake VBT DDC pin mapping fix (Rodrigo) * tag 'drm-intel-next-2017-10-23' of git://anongit.freedesktop.org/drm/drm-intel: (87 commits) drm/i915: Update DRIVER_DATE to 20171023 drm/i915/cnl: Map VBT DDC Pin to BSpec DDC Pin. drm/i915: Let's use more enum intel_dpll_id pll_id. drm/i915: Use existing DSI backlight ports info drm/i915: Parse DSI backlight/cabc ports. drm/i915: Skip waking the device to service pwrite drm/i915/crt: split compute_config hook by platforms drm/i915: remove g4x lowfreq_avail and has_pipe_cxsr drm/i915: Drop the redundant hdmi prefix/suffix from a lot of variables drm/i915: Unify error handling for missing DDI buf trans tables drm/i915: Centralize the SKL DDI A/E vs. B/C/D buf trans handling drm/i915: Kill off the BXT buf_trans default_index drm/i915: Pass encoder type to cnl_ddi_vswing_sequence() explicitly drm/i915: Integrate BXT into intel_ddi_dp_voltage_max() drm/i915: Pass the level to intel_prepare_hdmi_ddi_buffers() drm/i915: Pass the encoder type explicitly to skl_set_iboost() drm/i915: Extract intel_ddi_get_buf_trans_hdmi() drm/i915: Relocate intel_ddi_get_buf_trans_*() functions drm/i915: Flush the idle-worker for debugfs/i915_drop_caches drm/i915: adjust get_crtc_fence_y_offset() to use base.y instead of crtc.y ...
