This is not a good description of a device property. DT entries are supposed to described the hardware, not talk about how to use it. When you say that the bcm63xx doesn't support over-current reporting, what exactly do you mean? Do you mean that sometimes the hardware turns on the over-current bit when an over-current isn't actually present? Or do you mean something else?
