Ah sorry for the confusion, I misunderstood. I was talking about the
label, not the name, of the node.

So the labels for the gpio banks are 'gpio2' etc. The names are
'gpio@123456' etc. And yes, here the name should be 'gpio@22' as you said.

I didn't see any rules about the labels in the ePARP doc, so I guess
'tca6424a' would be a valid one. Maybe not a good one, though,
especially if there are multiple tca6424a chips on the board (I need to
check).
