Hi Bjorn,

Thanks for the review. Please find my comments inline.

I had looked at the sample from hi6220 for coresight and
decided to keep sdm845 coresight dtsi in separate file as it
would look much cleaner than mixing it with main dtsi file.
Also I guess it would make coresight topology more understandable
if we keep it separately (plus there are about 400+ lines of coresight
dt entries). Is there any reason for wanting coresight entries merged
into sdm845.dtsi file? If you still prefer it, I can make the
change in the next version.

I had mentioned this dependency in the cover letter. But I suppose
I can mention it here as well.

Thanks,
Sai
