Put ranges after reg, if they are needed. Are they needed, BTW?

ranges is after reg, which is after compatible, so here it is the second

Do you mean warnings generated by running "make W=1"? I tried just now
and didn't see warnings on this dts.

No, I meant `dtbs_check W=1` or W=1 coming from dtc (dtbs).

Yes, I just run "make W=1 dtbs",  also have tried `dtbs_check W=1`,
didn't see warnings on ums9620-2h10.dtb

Ah, because it does not even compile!

This was never tested and never built on the upstream kernel. Please
work on upstream, not on downstream fork.

The patch was generated from a middle commit (that was my mistake of course).

But I've fixed the issue. I ran the command just now according to your
comments, and didn't see the warnings on this dtb.

If I'm missing something, please correct me.

Thanks,
Chunyan

You don't have unit address for soc node, but could be fine if
address/size cells match. Don't remember, but also cannot verify because
it does not build. :(
