[PATCH 2/2] drm/tegra: Support semi-planar formats on Tegra114+
Thierry Reding

Wed Jan 12 08:48:28 UTC 2022
From: Thierry Reding <treding at nvidia.com>
The NV12, NV21, NV16, NV61, NV24 and NV42 formats are supported by
Tegra114 and later display hardware. Add the necessary programming to
allow them to be used.
