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)
