This series adds dts support for the Arm Morello System Development
Platform.

Do we actually need the dts for this board?

I have one on my desk; it boots vanilla Debian 12 via UEFI + ACPI just
fine, with the Debian 6.1.0-13-arm64 kernel.

Is there something that we can only do with the DT? i.e. some
functionality that isn't exposed via ACPI?

How do you expect this DT to be used?

There are functionalities that are not exposed via ACPI, e.g. gpu, dpu, i2c for
the phy, etc. My aim to have upstream support for all the hardware exposed by
the platform.

Does this address some of your concerns ? I do understand some of these
are not well addressed in ACPI and hence people use DT as an alternative.

Yep; I'm happy with this so long as there's an actual functional reason
to have the DT, which it seems there is.

It would have been nice for that to be spelled out a bit clearer in the
cover / commit messages, but that's not important and doesn't need a
respin.

I can add that info in my pull request as it is very valid point. One needs
to know why we are pushing DTS now after couple of years after the boards
are available and why DT over ACPI which is shipped with the device.

I was thinking of queuing this in -next if all the bindings are acked.
Let me know if you still have concerns and would like to avoid getting
these merged. I will hold off then.

No need to hold off.

Sorry for the confusion; I should have been clearer with my questions.

No confusion as such, good to ask explicitly and get the motivation for
this series captured on the list. Since I had gone through this motion
even with N1SDP which for some reasons I don't know didn't appear on the
list, I didn't ask it and implicitly assumed similar reasoning.

So, it is good that you asked and got it answered for wider audience here.
