Data Structures
struct	emul_link_for_bus
	Structure uniquely identifying a device to be emulated. More...
struct	emul_list_for_bus
	List of emulators attached to a bus. More...
struct	no_bus_emul
	Emulator API stub when an emulator is not actually placed on a bus. More...
struct	emul
	An emulator instance - represents the target emulated device/peripheral that is interacted with through an emulated bus. More...
union	emul::bus
	Pointer to the emulated bus node. More...

Macros
#define	EMUL_DT_NAME_GET(node_id)   _CONCAT(__emulreg_, node_id)
	Use the devicetree node identifier as a unique name.
#define	EMUL_DT_DEFINE(node_id, init_fn, data_ptr, cfg_ptr, bus_api, _backend_api)
	Define a new emulator.
#define	EMUL_DT_INST_DEFINE(inst, ...)   EMUL_DT_DEFINE(DT_DRV_INST(inst), __VA_ARGS__)
	Like EMUL_DT_DEFINE(), but uses an instance of a DT_DRV_COMPAT compatible instead of a node identifier.
#define	EMUL_DT_GET(node_id)   (&EMUL_DT_NAME_GET(node_id))
	Get a const struct emul* from a devicetree node identifier.
#define	EMUL_DT_GET_OR_NULL(node_id)    COND_CODE_1(DT_NODE_HAS_STATUS_OKAY(node_id), (EMUL_DT_GET(node_id)), (NULL))
	Utility macro to obtain an optional reference to an emulator.

Typedefs
typedef int(*	emul_init_t) (const struct emul *emul, const struct device *parent)
	Standard callback for emulator initialisation providing the initialiser record and the device that calls the emulator functions.

Enumerations
enum	emul_bus_type {   EMUL_BUS_TYPE_I2C , EMUL_BUS_TYPE_ESPI , EMUL_BUS_TYPE_SPI , EMUL_BUS_TYPE_MSPI ,   EMUL_BUS_TYPE_UART , EMUL_BUS_TYPE_NONE }
	The types of supported buses. More...

Functions
int	emul_init_for_bus (const struct device *dev)
	Set up a list of emulators.
const struct emul *	emul_get_binding (const char *name)
	Retrieve the emul structure for an emulator by name.
