Merge tag 'drm/tegra/for-5.9-rc1' of ssh://git.freedesktop.org/git/tegra/linux into drm-next
drm/tegra: Changes for v5.9-rc1
This set of patches contains a few preparatory patches to enable video
capture support from external camera modules. This is a dependency for
the V4L2 driver patches that will likely be merged in v5.9 or v5.10.
On top of that there are a couple of fixes across the board as well as
some improvements.
From a feature point of view this also adds support for horizontal
reflection and 180° rotation of planes.
