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. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Alim Akhtar --- I propose to take the patch through Samsung SoC (me).
