Hi Vladimir
There should be a compatible string here for the board. It looks like
you will also need to add Methode as a vendor to
Documentation/devicetree/bindings/vendor-prefixes.txt.

It is normal to have a name here, indicating what the LED is for, its
colour, etc.

These don't appear to be used anywhere.

The SFP driver will export the 'eeprom' via ethtool --module-info.
Please don't add a standard EEPROM.

This adds initial support for micro-DPU (uDPU) board which is based on
Armada-3720 SoC. micro-DPU is the single-port FTTdp distribution point
unit made by Methode Electronics which offers complete modularity with
replaceable SFP modules both for uplink and downlink (G.hn over
twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable).
On-board features:
- 512 MiB DDR3
- 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC
- USB 2.0 Type-C connector
- 4GB eMMC
- ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type)

v2:
- add compatible string for the uDPU board
- add names and labels for the LEDs
- remove unused mdio node
- remove eeprom nodes

Compatible strings are sorted as most specific to most generic. So
"methode,udpu" should be first. "marvell,armada-3720-db" can probably
be dropped.

- fix Methode copyright (use Methode Electornics instead of Methode)
- sort compatible string by relevance, remove armada-3720-db and
armada3710 to keep it generic

Hi Vladimir
Ah, i did not notice early. You need to Cc: the Marvell mvebu
maintainers. They are the ones who will accept this patch.

I'm a bit out of date with dtc warnings. I think the @487 will
generate a warning because there is no reg property?
Gregory, do you know?
Thanks

I confirm that if there is no reg then there should not have a @XXX.

This adds initial support for micro-DPU (uDPU) board which is based on
Armada-3720 SoC. micro-DPU is the single-port FTTdp distribution point
unit made by Methode Electronics which offers complete modularity with
replaceable SFP modules both for uplink and downlink (G.hn over
twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable).
On-board features:
- 512 MiB DDR3
- 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC
- USB 2.0 Type-C connector
- 4GB eMMC
- ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type)

v2:
- add compatible string for the uDPU board
- add names and labels for the LEDs
- remove unused mdio node
- remove eeprom nodes
v3:
- update copyright year for Methode and Telus
- fix Methode copyright (use Methode Electornics instead of Methode)
- sort compatible string by relevance, remove armada-3720-db and
armada3710 to keep it generic
v4:
- add generic names for LEDs since they don't use regs
- add 'partitions' section to standarize with other A37xx/A7K/A8K dts's
- remove usb3 phandle because of the broken usb_phy (previously used on
Marvell linux repo) and since usb support is still work in progress

But here you say that the card is not removable:

Can you explain what do you expect to be connected here?
