parallel and operating them independently.

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

The driver builds multiplexer controllers for bitfields in either
|
|
|
|
|
a syscon register or a driver regmap register. For N bit wide

|

|

bitfields, there will be 2^N possible multiplexer states.
