Well, I'm assuming that the alias property names will follow the current
convention of xxxxnn where xxxx is a name and nn is a number.  No dashes or
other punctuation.

As an alternative to cell-index or device-id for enumerating devices.  The
consensus from the '"cell-index" vs. "index" vs. no index in I2C device nodes'
thread is that aliases are to be used to enumerate devices.
