[PATCH 0/2] drm/tegra: Support YVU420

[Aaron Kling via B4 Relay]

This is not directly supported by the display controller hardware.
However, this can be handled efficiently by just passing the chroma
planes to the hardware backwards and reporting it as yuv420.

The format is required by AOSP for software decoded video playback among
other things. An attempt was made to handle this in gralloc by swapping
the chroma planes there, but it wasn't working. This kernel
implementation is working and is more generic anyways. This has been
verified on a SHIELD TV 2019 Pro for the tegradc path and a Jetson TX2
NX for the nvdisplay path.
