Merge tag 'drm-intel-next-2018-07-09' of git://anongit.freedesktop.org/drm/drm-intel into drm-next

Higlights here goes to many PSR fixes and improvements; to the Ice lake work with
power well support and begin of DSI support addition. Also there were many improvements
on execlists and interrupts for minimal latency on command submission; and many fixes
on selftests, mostly caught by our CI.

General driver:
- Clean-up on aux irq (Lucas)
- Mark expected switch fall-through for dealing with static analysis tools (Gustavo)

Gem:
- Different fixes for GuC (Chris, Anusha, Michal)
- Avoid self-relocation BIAS if no relocation (Chris)
- Improve debugging cases in on EINVAL return and vma allocation (Chris)
- Fixes and improvements on context destroying and freeing (Chris)
- Wait for engines to idle before retiring (Chris)
- Many improvements on execlists and interrupts for minimal latency on command submission (Chris)
- Many fixes in selftests, specially on cases highlighted on CI (Chris)
- Other fixes and improvements around GGTT (Chris)
- Prevent background reaping of active objects (Chris)

Display:
- Parallel modeset cleanup to fix driver reset (Chris)
- Get AUX power domain for DP main link (Imre)
- Clean-up on PSR unused func pointers (Rodrigo)
- Many PSR/PSR2 fixes and improvements (DK, Jose, Tarun)
- Add a PSR1 live status (Vathsala)
- Replace old drm_*_{un/reference} with put,get functions (Thomas)
- FBC fixes (Maarten)
- Abstract and document the usage of picking macros (Jani)
- Remove unnecessary check for unsupported modifiers for NV12. (DK)
- Interrupt fixes for display (Ville)
- Clean up on sdvo code (Ville)
- Clean up on current DSI code (Jani)
- Remove support for legacy debugfs crc interface (Maarten)
- Simplify get_encoder_power_domains (Imre)

Icelake:
- MG PLL fixes (Imre)
- Add hw workaround for alpha blending (Vandita)
- Add power well support (Imre)
- Add Interrupt Support (Anusha)
- Start to add support for DSI on Ice Lake (Madhav)
