Merge tag 'drm-misc-next-2020-06-26' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.9:

Cross-subsystem Changes:
- Improve dma-buf docs.

Core Changes:
- Add NV15, Q410, Q401 yuv formats.
- Add uncompressed AFBC modifier.
- Add DP helepr for reading Ignore MSA from DPCD.
- Add missing panel type for some panels
- Optimize drm/mm hole handling.
- Constify connector to infoframe functions.
- Add debugfs for VRR monitor range.

Driver Changes:
- Assorted small bugfixes in panfrost, malidp, panel/otm8009a.
- Convert tfp410 dt bindings to yaml, and rework time calculations.
- Add support for a few more simple panels.
- Cleanups and optimizations for ast.
- Allow adv7511 and simple-bridge to be used without connector creation.
- Cleanups to dw-hdmi function prototypes.
- Remove enabled bool from tiny/repaper and mipi-dbi, atomic handles it.
- Remove unused header file from dw-mipi-dsi
- Begin removing ttm_bo->offset.
