The difference is only in the compatible. Best regards, Krzysztof

Maybe Srini would know more. Indeed, looking at downstream DTS this is closer to SM8250 and SM8350 than SC8280xp, with some interesting differences. But if you bring it up, you also might fix SM8350, to which I looked a bit but then gave up. Anyway, with the example staying or removed: Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Best regards, Krzysztof

SM6115 (and its derivatives or similar SoCs) have a LPASS clock controller block which provides audio-related resets. Add bindings for it.
