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) * tag 'drm-misc-next-2017-04-07' of git://anongit.freedesktop.org/git/drm-misc: (77 commits) Revert "drm: Don't allow interruptions when opening debugfs/crc" drm: Only take cursor locks when the cursor plane exists drm/vmwgfx: Fix fbdev emulation using legacy functions drm/rockchip: Shutdown all crtcs when unbinding drm drm/rockchip: Reorder drm bind/unbind sequence drm/rockchip: analogix_dp: Disable clock when unbinding drm/rockchip: vop: Unprepare clocks when unbinding drm/rockchip: vop: Enable pm domain before vop_initial drm/rockchip: cdn-dp: Don't unregister audio dev when unbinding drm/rockchip: cdn-dp: Don't try to release firmware when not loaded drm: bridge: analogix: Destroy connector & encoder when unbinding drm: bridge: analogix: Disable clock when unbinding drm: bridge: analogix: Unregister dp aux when unbinding drm: bridge: analogix: Detach panel when unbinding analogix dp drm: Don't allow interruptions when opening debugfs/crc drm/virtio: don't leak bo on drm_gem_object_init failure drm: bridge: dw-hdmi: fix input format/encoding from plat_data drm: omap: use common OF graph helpers drm: convert drivers to use drm_of_find_panel_or_bridge drm: convert drivers to use of_graph_get_remote_node ...
