Ok, your other patch makes more sense now.

How about we put all serial devices into one pq3-duart.dtsi file, and
let the parent dtsi file reference just the ones that it needs?

there isn't an option to do that w/dtc

What about making all the nodes disabled by default, and then the soc.dtsi
or si.dtsi file can re-enable them?

Its still a bit problematic in that I don't want nodes to exist that aren't in the SoC.
