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.

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.
