19 parallel and operating them independently.

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

44 The driver builds multiplexer controllers for bitfields in a syscon
45 register. For N bit wide bitfields, there will be 2^N possible
46 multiplexer states.
