drm-misc-next for 5.7: UAPI Changes: - lima: Add support for heap buffers Cross-subsystem Changes: Core Changes: - Implement mode_config mode_valid for memory constrained drivers - Bus format negociation between bridges - Consolidate fake vblank events for drivers without vblank interrupts - drm/bufs: dma_alloc related cleanups - drm/dp_mst: Various fixes - drm/print: New drm_device based print helpers - Thomas is a drm-misc maintainer now! Driver Changes: - DPMS cleanups for atomic drivers - Removal of owner field in SPI tinydrm drivers - Removal of explicit dependency on DT for tinydrm drivers - Conversion to YAML schemas for DT bindings - tidss: New driver - virtio: various reworks and fixes - Our usual dozen or so new panels or bridges Signed-off-by: Dave Airlie <airlied@redhat.com> From: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20200210093421.xu4sofldm6wm6xq6@gilmour.lan
