I think the DT Maintainers and checkpatch.pl maintainers need to think about this. Maybe a regex would be enough in Documentation/devicetree/bindings/mtd/m25p80.txt? For the moment i would suggest adding a vendor prefix, but nothing more. > >> + /* > >> + * The Ethernet nodes are not ordered by > >> + * address on purpose.

As there already is in armada-370-xp.dtsi aliases { eth0 = ð0; eth1 = ð1; }; eth0: ethernet@70000 { } eth1: ethernet@74000 { } This at least works for i2c devices. The pdev->id is set using the alias number.
