Grant, but isn't it true that the final device's name would not be the DT
way of names? It would simply be "stmpe810" for us and so if we have
multiple instances of stmpe on a board, we need to distinguish them
ourselves? One way for that was passing id for these instances, which
would finally be used, when we create platform devices for sub-modules
of stmpe (gpio, keypad, ts, etc).
