| 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. |

| parallel and operating them independently. |

| 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. |
