I prefer that you actually describe what these are connected to. I
presume there will be more DPTX instances enabled for this board? If
that's the case, let's mention here that this is just a subset.

Please wait with resubmitting this patch until the base dtsi has landed
(with its new name).

status last please.

I prefer that you actually describe the connectors, like I did on
sa8295p-adp. In particular if there's a bunch of connectors on this
board.

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: base-commit 7f3a635117b377cb90b67757cb46de12ce8aa24e not known, ignoring
Base: attempting to guess base-commit...
Base: failed to guess base
Deps: looking for dependencies matching 3 patch-ids

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
