| Enable the emulated GPIO driver. Mainly used for testing, this |
| driver allows for an arbitrary number of emulated GPIO controllers |
| to be instantiated. Furthermore, the emulated pins can be "wired" |
| using the regular GPIO callback API and the additional API |
| available in drivers/gpio/gpio_emul.h . Configuration for each |
| GPIO instance is accomplished using device tree and an example of |
| such a configuration is in |
| tests/drivers/gpio/gpio_basic_api/boards/native_posix_64.overlay |
| If unsure, say N. |
