There was no further comments on my proposal to skip touching sc8280xp:
https://lore.kernel.org/alsa-devel/20240125153110.410295-1-krzysztof.kozlowski@linaro.org/T/#mc45e487f25a2d6388b5c478b1b7827b113640f4f

so I will go with that approach. Please ignore this DTS patch. I will
send ASoC changes which won't affect sc8280xp.

Best regards,
Krzysztof
