Merge tag 'drm-misc-next-2017-04-07' of git://anongit.freedesktop.org/git/drm-misc into drm-next

Last drm-misc-next pull req for 4.12

Core changes:
 - fb_helper checkpatch cleanup and simplified _add_one_connector() (Thierry)
 - drm_ioctl and drm_sysfs improved/gained documentation (Daniel)
 - [ABI] Repurpose reserved field in drm_event_vblank for crtc_id (Ander)
 - Plumb acquire ctx through legacy paths to avoid lock_all and legacy_backoff
   (Daniel)
 - Add connector_atomic_check to check conn constraints on modeset (Maarten)
 - Add drm_of_find_panel_or_bridge to remove boilerplate in drivers (Rob)

Driver changes:
 - meson moved to drm-misc (Neil)
 - Added support for Amlogic GX SoCs in dw-hdmi (Neil)
 - Rockchip unbind actually cleans up the things bind initializes (Jeffy)
 - A couple misc fixes in virtio, dw-hdmi

NOTE: this also includes a backmerge of drm-next as well rc5 (we needed vmwgfx
      as well as the new synopsys media formats)
