Well, the "reg" property is fine for the common cases of devices with
one IO (or MMIO) range, no confusion possible, or PCI since it encodes
the BAR number. For other cases, especially random embedded stuff that
maps several regions of memory, it's a bit harder since we go back to
the need of having "somebody" define which region is which.
Indeed. You choose based on the common case and eventually there will
be some case that stretches the boundaries.
I suppose that, if the problem became severe enough, one could invent a
new "reg-names" property, a list of strings naming the reg entries.
