Multiplexer controller subsystem. Multiplexers are used in a
variety of settings, and this subsystem abstracts their use
so that the rest of the kernel sees a common interface. When
multiple parallel multiplexers are controlled by one single
multiplexer controller, this subsystem also coordinates the
multiplexer accesses.
To compile the subsystem as a module, choose M here: the module will
be called mux-core.

help
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
be called mux-gpio.
