From: Thierry Reding <redacted>

Add the memory-region and memory-region-names properties to the bindings
for the display controllers and the host1x engine found on various Tegra
generations. These memory regions are used to access firmware-provided
framebuffer memory as well as the video protection region.

See https://patchwork.kernel.org/project/devicetree/patch/20260701-tegra-vpr-v3-2-d80f7b871bb4@nvidia.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
