Merge tag 'drm-misc-next-2017-05-16' of git://anongit.freedesktop.org/git/drm-misc into drm-next

UAPI Changes:
- Return -ENODEV instead of -ENXIO when creating cma fb w/o valid gem (Daniel)
- Add aspect ratio and custom scaling propertis to connector state (Maarten)

Cross-subsystem Changes:
- None

Core Changes:
- Add Laurent as bridge reviewer and Andrzej as bridge maintainer (Archit)
- Maintain new STM driver through -misc (Yannick)
- Misc doc improvements (as is tradition) (Daniel)
- Add driver-private objects to atomic state (Dhinakaran)
- Deprecate preclose hook in modern drivers (use postclose) (Daniel)
- Add hwmode to vblank struct. This fixes mode access in irq context and reduced
  a bunch of boilerplate (Daniel)

Driver Changes:
- vc4: Add out-fence support to vc4 V3D rendering (Eric)
- stm: Add stm32f429 display hw and am-480272h3tmqw-t01h panel support (Yannick)
- vc4: Remove 256MB cma limit from vc4 (Eric)
- dw-hdmi: Disable audio when inactive, instead of always enabled (Romain)
- zte: Add support for VGA to the ZTE driver (Shawn)
- i915: Track DP MST bandwidth and check it in atomic_check (Dhinakaran)
- vgem: Enable gem dmabuf import iface to facilitate ion testing (Laura)
- vc4: Add support for Cygnus (new dt compat string + couple bug fixes) (Eric)
- pl111: Add driver for pl111 CLCD display controller (Eric/Tom)
- vgem: Subclass drm_device instead of standalone platform device (Chris)
