Merge tag 'drm-intel-next-2018-02-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next

UAPI Changes:

- Userspace whitelist register GEN9_SLICE_COMMON_ECO_CHICKEN1 for GLK (Kenneth)
- Non-existent PMU counters are not placed to sysfs (Tvrtko)
- Add a note to deprecate I915_SET_COLORKEY_NONE and ignore it (Ville)
	* Intel DDX never ended using it, and implementation was wonky

Core Changes:

- Moved away from struct timeval into ktime_t in prep for 2038 (Arnd)
	* Merged the i915 portion through drm-tip, no core dependencies

Driver Changes:

- Base support for Icelake and Icelake PCH (Anusha, Rodrigo, Mahesh, Paulo, James, Kelvin)
- Add AUX-F port support for Cannonlake (Rodrigo)
- New DMC firmware for 1.07 Cannonlake (Anusha)
	* Go to linux-firmware.git to get it
- Reject non-cursor planes nearly (3 px) out of screen on GLK/CNL (Imre)
- Y/Yf modifiers restored for SKL+ sprites (Ville)
- Compressed framebuffer support for sprites (Ville)
- Tune down overly aggressive shrinking (Chris)
- Shrink kmem caches when GPU is idle (Chris)
- EDID bit-banging fallback for HDMI EDID (Stefan)
- Don't boost the GPU when the waited request is already running (Chris)
- Avoid GLK/BXT CDCLK frequency locking timeouts (Imre)
- Limit DP link rate according to VBT on CNL+ (Jani)
- Skip post-reset request emission if the engine is not idle (Chris)
- Report any link training error on a fixed eDP panel as errors (Manasi)
- DSI panel fixes for Bay Trail (Hans)
- Selftest additions and improvements (Chris, Matt)
- DMA fence test additions and accompanying fixes (Chris)
- Power domain vs. register access fix (Maarten)
- Squelch warnings for people with teensy framebuffers (stride < 512) (Maarten)
- Increase Render/Media power gating hysteresis for Gen9+ (Chris)
- HDMI vswing display workaround for Gen9+ (Ville)
- GuC code cleanup and lockdep fixes (Sagar, Michal Wa.)
- Continuously run hangcheck for simplicity (Chris)
- Execlist debugging improvements (Chris)
- GuC debugging improvements (Sujaritha, Michal Wa., Sagar)
- Command parser boundary checks (Michal Srb)
- Add a workaround for 3DSTATE_SAMPLE_PATTERN on CNL (Rafael)
- Fix PMU enabling race condition (Tvrtko)
- Usual smaller testing and debugging improvements
