OK.

ePAPR says: "If the node has no reg property, the unit-address may be
omitted if the node name alone differentiates the node from other nodes
at
the same level in the tree."

I could use 'gpio@bank-a', it is allowed by the spec. Or do you prefer
'gpio@0'?

I'll wait from some feedback on the other patches then send a v5.

Thanks,
