I had a quick, and I mean quick, look through the arm smarc dtsi and none of them appeared to be a 1:1 match with what I see here. I assume that's got something to do with the "minimal" in the patch's subject line, and some re-org of the arm files would be required? In any case, you've not introduced any more dtbs_check detectable issues so you're good in my book whichever way you do it. Reviewed-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
