This is really a question to the DT Maintainers. This is a carrier
board for a standardised Com express type 7 board. In theory, you
should be able to plug any Com Express module into it, not just
Marvells. So should the compatible list just have a compatible for the
carrier itself? Not the module which would normally be mounted in it?
Should the carrier have a .dtsi file describing it? And then we have a
.dts file which combines the module .dtsi and the carrier .dtsi?
Sorry i did not ask this earlier, i was thinking more about SolidRuns
systems, which tend to have custom SOMs and customs carriers, so you
can only really mount one particular SOM into one particular
carrier. But that is not true here.
Andrew

This description is i think technically wrong. You have the
combination of the carrier and the module.

No underscores in compatibles. Do you see them anywhere? Please use
existing, recent code as start of your contributions, not something
buggy 5 years old.

Except wrong naming for compatible, I really do not understand what you
want to add here. If AC5X is the carrier, what is the model name of
entire product? If AC5X is not the carrier, where it the carrier?

Yes, because there are some common parts of the carrier board.

Depends, how this is organized depends on possible re-usage etc. Usually
answer is: yes, carrier board should have DTSI.

Please order your patches correctly, so bindings come before their
users. You cannot have other way.
