Implying its Elba specific is misleading. Compatibles must be specific. https://elixir.bootlin.com/linux/v6.1-rc1/source/Documentation/devicetree/bindings/writing-bindings.rst#L42 If this is SoC part it must match SoC. What is misleading in this? Why Pensando is different than all other SoCs (I am really getting tired everytime asking why people think their solution is special)? If this is not part of the SoC, then your commit msg is misleading. Maybe bindings as well, so rework it. Best regards, Krzysztof
