| 18 | The driver supports both operating the three multiplexers in |
| 19 | parallel and operating them independently. |

| 21 | To compile the driver as a module, choose M here: the module will |
| 22 | be called mux-adg792a. |

| 29 | |
| 30 | The driver builds a single multiplexer controller using a number |
| 31 | of gpio pins. For N pins, there will be 2^N possible multiplexer |
| 32 | states. The GPIO pins can be connected (by the hardware) to several |
| 33 | multiplexers, which in that case will be operated in parallel. |
| 34 | |
| 35 | To compile the driver as a module, choose M here: the module will |
| 36 | be called mux-gpio. |
