"IPC request between" does not specify who sends the request. Host or DSP? See existing bindings for some better examples, e.g.: Documentation/devicetree/bindings/serial/nvidia,tegra194-tcu.yaml which clearly states who receives from who. > + > + mbox-names: > + items: > + - const: rep > + - const: req tx/rx Best regards, Krzysztof
