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 compatibles specific to each SoC in front of all old-SoC-like compatibles. > This will also help reviews of new code using existing DTS as template.
