drm-misc-next for 4.17:

UAPI Changes:
- Validate mode flags + type (Ville)
- Deprecate unused mode flags PIXMUX, BCAST (Ville)
- Deprecate unused mode types BUILTIN, CRTC_C, CLOCK_C, DEFAULT (Ville)

Cross-subsystem Changes:
- MAINTAINERS: s/Daniel/Maarten/ for drm-misc (Daniel)

Core Changes:
- gem: Export gem functions for drivers to use (Samuel)
- bridge: Introduce bridge timings in drm_bridge (Linus)
- dma-buf: Allow exclusive fence to be bundled in fence array when
	   calling reservation_object_get_fences_rcu (Christian)
- dp: Add training pattern 4 and HBR3 support to dp helpers (Manasi)
- fourcc: Add alpha bit to formats to avoid driver format LUTs (Maxime)
- mode: Various cleanups + add new device-wide .mode_valid hook (Ville)
- atomic: Fix state leak when non-blocking commits fail (Leo)
	  NOTE: IIRC, this was cross-picked to -fixes so it might fall out
- crc: Allow polling on the data fd (Maarten)

Driver Changes:
- bridge/vga-dac: Add THS8134* support (Linus)
- tinydrm: Various MIPI DBI improvements/cleanups (Noralf)
- bridge/dw-mipi-dsi: Cleanups + use create_packet helper (Brian)
- drm/sun4i: Add Display Engine frontend support (Maxime)
- drm/sun4i: Add zpos support + increase num planes from 2 to 4 (Maxime)
- various: Use drm_mode_get_hv_timing() to fill plane clip rectangle (Ville)
- stm: Add 8-bit clut support, add dsi phy v1.31 support, +fixes (Phillipe)
