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 at 123456' etc. And yes, here the name should be 'gpio at 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).
