  19           parallel and operating them independently.

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

  54           The driver builds multiplexer controllers for bitfields in either
  55           a syscon register or a driver regmap register. For N bit wide
  56           bitfields, there will be 2^N possible multiplexer states.
