 Thank you very much. Indeed, this looks very similar. By the way, should i document smsc over sromc in the same manner, writing
devicetree/bindings/net/sromc-eth.txt?

 This is a short reply for now, i'll make longer one (or just a new version) after studying these existing bindings and trying to
apply them.

 So, if you look at gpmc-eth.txt, you'll see that this approach is perfectly valid (this is a reply to another msg, just don't want
to post one more single-line reply).
