As a comment not affecting my ack in any way: At the top-level, we place all the child nodes into "array container" nodes named "pads" and "ports". This is nice since it separates different types of child nodes and allows easily adding more types of child nodes in the future without interference, and in a way that allows us to explicitly know what each node is without having to interpret its name or compatible value to do so. However, we haven't done this with the per-lane child nodes inside each pad. If we were to rev the design, I'd be tempted to suggest:

padctl@0,7009f000 {
pads {
usb2 {
lanes { // This level is new
usb2-0 {
