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.
