0019 parallel and operating them independently.

0038 GPIO-controlled Multiplexer controller.

0040 The driver builds a single multiplexer controller using a number
0041 of gpio pins. For N pins, there will be 2^N possible multiplexer
0042 states. The GPIO pins can be connected (by the hardware) to several
0043 multiplexers, which in that case will be operated in parallel.
