I agree here. What exactly is common in the real hardware between IDP
and RB3? Commit msg does not explain it, so I do not see enough
justification for common file. Just because some DTS looks similar for
different hardware does not mean you should creat common file.

@Dmitry/@Krzysztof,

Thank you for reviewing the RFC, we wanted to continue the
suggestion/discussion given on [1] , where we discussed that this
qcm6490 is going to be targeted for IOT segment and will have different
memory map and it is going to use some of co-processors like adsp/cdsp
which chrome does not use.

So to your question what is common between RB3 and IDP, mostly they will
share common memory map(similar to [2]) and regulator settings and both

The question was what is common hardware, not common in your DTS.

Got your point.
Let me know if you agree with the suggestion shared here

will use adsp/cdsp etc., we will be posting the memory map changes as
well in coming weeks once this RFC is acked.

Sorry, that's not common part of hardware.

Best regards,
Krzysztof
