GPIO-controlled Multiplexer controller.
|
|
|
|
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.

To compile the driver as a module, choose M here: the module will
