Isn't there comment just few lines above your edit? Comment saying DON'T?

yes, I saw this "DON'T" comment, but if I remove "qcom,sm4450-smmu-500" 
from sm4450.dtsi and this arm,smmu.yaml, will get DT check warning about 

Why would you remove it?

this, this warning cannot be find after add "qcom,sm4450-smmu-500" from 
sm4450.dtsi and this arm,smmu.yaml, so update this patch again.

What does the comment say? Why are you adding it to the enum which asks
- do not add to this enum, but add to other above and below?


Best regards,
Krzysztof
