Historically we kept the old (block's) compatible only. This works fine and there is no bug here, however guidelines expressed in Documentation/devicetree/bindings/writing-bindings.rst state that: 1. Compatibles should be specific. 2. We should add new compatibles in case of bugs or features. Add Tesla FSD compatible specific to be used with an existing fallback. Signed-off-by: Krzysztof Kozlowski Acked-by: Rob Herring Acked-by: Wolfram Sang --- I propose to take the patch through Samsung SoC (me).
