Emlid Neutis N5 is a SoM based on Allwinner H5, has a WiFi & BT
module, DDR3 RAM and eMMC.

- add neutis n5 dtsi file for SoM needs
- add neutis devboard dts file
- add neutis devboard target to dtb makefile
- new vendor prefix - emlid

Your commit prefix is wrong, it should be arm64: dts: allwinner:

This should be in a separate patch.

Do you need the two emlid there? What comes before the comma is the
vendor, while what is after is the model.

Also, please align those strings

I guess this is for bluetooth? Have you tested serdev drivers?

Also, I have a general comments, and it really depends on what your
intention about the board ecosystem is. Do you expect the SOM to be
swappable in multiple boards, or do you expect to send it as something
that is just fixed into a daughter board?

In the former case, you probably want to use overlays instead. In the
latter, you're fine.

You misunderstand: The point would be to use, e.g., "emlid,neutis-n5"
instead of "emlid,emlid-neutis-n5" with duplicate "emlid,emlid-". It is
orthogonal to having multiple compatible strings.

Not quite, we're missing a child node within uart1 for a serdev driver.
Is there no such driver yet for your Bluetooth chipset, or did you not
yet check?

What about just keeping the common nodes enabled in a SoM .dts, so that
the average board doesn't need an Overlay for booting?

@Maxime/Rob, is it possible to merge .dtso files these days? If not,
could that be considered in the big dts Makefile refactoring? :)

Cheers,
Andreas

I guess the fundamental difference would be if the SoM can be run
free-standing or not. If it is, then overlays would be best. If not,
then I'm fine with using the include like Aleksandr has used.

I don't really know what is that big dts Makefile refactoring you're
mentionning, but I don't think we can merge dtso before having the DT
connectors in place.

Oh, I agree. No need to duplicate "emlid". Thank you!

Got it. I haven't checked a serdev driver.

Maxim, the SoM can't be run without a motherboard. According to your last message
I don't change dts files, right?

Yep, that works for me.
