> Subject: [PATCH 01/17] dt-bindings: hwinfo: samsung,exynos-chipid: add
> specific compatibles for existing SoC
>
> Samsung Exynos SoC reuses several devices from older designs, thus
> 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 compatibles specific to each SoC in front of all old-SoC-like compatibles.
