| 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 amlogic-mux-gpio. |
