18 parallel and operating them independently.

29 The driver builds a single multiplexer controller using a number
30 of gpio pins. For N pins, there will be 2^N possible multiplexer
31 states. The GPIO pins can be connected (by the hardware) to several
32 multiplexers, which in that case will be operated in parallel.
