Subject: [PATCH 2/2] arm64: dts: marvell: add support for Methode eDPU

Methode eDPU is an Armada 3720 powered board based on the Methode uDPU.

They feature the same CPU, RAM, and storage as well as the form factor.

However, eDPU only has one SFP slot plus a copper G.hn port.

In order to reduce duplication, split the uDPU DTS into a common one.

You need also bindings for the board compatible. Someone should convert
the Documentation/devicetree/bindings/arm/marvell/armada-37xx.txt to YAML.

OK status is by default, why do you need it? Also, it goes as last property.

Ok, I can convert the SoC compatibles at least for now.
Any advice you can give me on how the handle the Espressobin boards
having multiple board-specific compatibles?
For example, Espressobin V7 has:
"globalscale,espressobin-v7", "globalscale,espressobin"

Can you give me an example of what would be appropriate here because the SFP
bindings example utilizes the same naming scheme as used here?

Ok, will split the DTSI and eDPU commits and fixup nodes in between.

It's not needed, I have not changed any nodes, they are just
copy/paste during the DTS split.
Will drop it in v2.

There are 2 SFP nodes in total, that is why they are named according
to the ethernet controller
to which they are connected.
uDPU has 2 SFP slots while eDPU has 1, so one was moved to uDPU DTS.

Understood, I did all of the fixups now before the split to make it clear.

Ah, then let it be. sfp-1 and sfp-2 would also work, but that's not
important.

Hm, but the node names were different in original DTS, so this is not a
simple split. In such case better to correct coding styles in one patch
(node names, status etc) and then perform the split. The split should
create the same output DTB, which is not the case here.
