Data Structures
struct	entropy_driver_api
	Entropy driver API structure. More...

Macros
#define	ENTROPY_BUSYWAIT   BIT(0)
	Driver is allowed to busy-wait for random data to be ready.

Typedefs
typedef int(*	entropy_get_entropy_t) (const struct device *dev, uint8_t *buffer, uint16_t length)
	Callback API to get entropy.
typedef int(*	entropy_get_entropy_isr_t) (const struct device *dev, uint8_t *buffer, uint16_t length, uint32_t flags)
	Callback API to get entropy from an ISR.

Functions
int	entropy_get_entropy (const struct device *dev, uint8_t *buffer, uint16_t length)
	Fills a buffer with entropy.
static int	entropy_get_entropy_isr (const struct device *dev, uint8_t *buffer, uint16_t length, uint32_t flags)
	Fills a buffer with entropy in a non-blocking or busy-wait manner.
