Merge tag 'drm-misc-next-2018-12-06' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
Final changes to drm-misc-next for v4.21: UAPI Changes: Core Changes: - Add dma_fence_get_stub to dma-buf, and use it in drm/syncobj. - Add and use DRM_MODESET_LOCK_BEGIN/END helpers. - Small fixes to drm_atomic_helper_resume(), drm_mode_setcrtc() and drm_atomic_helper_commit_duplicated_state() - Fix drm_atomic_state_helper.[c] extraction. Driver Changes: - Small fixes to tinydrm, vkms, meson, rcar-du, virtio, vkms, v3d, and pl111. - vc4: Allow scaling and YUV formats on cursor planes. - v3d: Enable use of the Texture Formatting Unit, and fix prime imports of buffers from other drivers. - Add support for the AUO G101EVN010 panel. - sun4i: Enable support for the H6 display engine.
