All new bindings must be in the DT-schema format (yaml files). This enables a lot of syntax checks and validation. We are slowly migrating away from the .txt based bindings. Also, for new bindings please follow the guide lines listed in Documentation/devicetree/bindings/submitting-patches.rst Consider including the bindings with the drivers using the bindings so things have a more natural split.
