There was some extra discussion on this patch that has ended up with a question about numbering nodes.
Current binding assumes that nodes should be numbered with independent suffix numbers like:
led-0 { };
led-1 { };
led-2 { };
Do you think this could / should be improved somehow?
One option I was thinking about was using:
led@0 { };
led@5 { };
where numbers ("0", "5") should match GPIO numbers.
Is that a valid solution and does it improve things to make it worth it?
