i2c-virtio represents a virtio I2C device and this patch adds binding
for the same. The i2c-virtio subnode can be part of a virtio,mmio node
and is based on its binding.

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
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.
