Merge tag 'drm-misc-next-2020-07-16' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v5.9: UAPI Changes: Cross-subsystem Changes: - Add ckoenig as dma-buf maintainer. - Revert invalid fix for dma-fence-chain, and fix selftest. - Add fixmes to amifb about APUS support. - Use array3_size in fbcon_prepare_logo, and struct_size() in alloc_apertures. - Fix leaks in neofb, fb/savage and omapfb. - Other small fixes to fb code. - Convert some dt bindings to schema for some panels, and fix simple-framebuffer dt example. Core Changes: - Add DRM_FORMAT_MOD_GENERIC_16_16_TILE as alias to DRM_FORMAT_MOD_SAMSUNG_16_16_TILE, as it can be used more generic. - Add support for multiple DispID extension blocks in edid. - Use https instead of http for some of the urls. - Use drm_* macros for logging in mipi-dsi and fb-helper. - Further cleanup ttm_mem_reg handling. - Remove duplicated words in comments. Driver Changes: - Use __drm_atomic_helper_crtc_reset in all atomic drivers. - Add Amlogic Video FBC support to meson and fourcc to core. - Refactor hisilicon's hibmc_drv_vdac. - Create a TXP CRTC for vc4. - Rework cursor support in ast. - Fix runtime PM in STM. - Allow bigger cursors in vkms. - Cleanup sg handling in radeon and amdgpu, and stop creating dummy gtt nodes with ttm fixed. - Rework crtc handling in mgag200. - Miscellaneous small fixes to meson, vgem, bridge/dw-hdmi, panel/auo,b116xw03, panel/LG LB070WV8, lima, bridge/sil_sii8620, virtio, tilcdc.
