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.
