Mainly used for testing, this 12 driver allows for an arbitrary number of emulated GPIO controllers 13 to be instantiated. Furthermore, the emulated pins can be "wired" 14 using the regular GPIO callback API and the additional API 15 available in drivers/gpio/gpio_emul.h . Configuration for each 16 GPIO instance is accomplished using device tree and an example of 17 such a configuration is in 18 tests/drivers/gpio/gpio_basic_api/boards/native_posix_64.overlay 19 If unsure, say N. 20
