you might also want to add the multi-master boolean property in
the binding.

We discussed this internally and weren't sure when it was required
because e.g. i2c-rcar and i2c-tegra don't have it documented in their
bindings. Is it still required if it is part of the dt-schema?
https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/i2c/i2c-controller.yaml

The i2c-imx.yaml has "unevaluatedProperties: false", which fill discard
every thing not in this yaml

If so, I will add it in the next version.

Yes, please.

Perfect, thanks for the explanation.
