Enumerations
enum	i3c_addr_slot_status {   I3C_ADDR_SLOT_STATUS_FREE = 0U , I3C_ADDR_SLOT_STATUS_RSVD , I3C_ADDR_SLOT_STATUS_I3C_DEV , I3C_ADDR_SLOT_STATUS_I2C_DEV ,   I3C_ADDR_SLOT_STATUS_MASK = 0x03U }
	Enum to indicate whether an address is reserved, has I2C/I3C device attached, or no device attached. More...

Functions

	Initialize the I3C address slots struct.
void	i3c_addr_slots_set (struct i3c_addr_slots *slots, uint8_t dev_addr, enum i3c_addr_slot_status status)
	Set the address status of a device.
enum i3c_addr_slot_status	i3c_addr_slots_status (struct i3c_addr_slots *slots, uint8_t dev_addr)
	Get the address status of a device.
bool	i3c_addr_slots_is_free (struct i3c_addr_slots *slots, uint8_t dev_addr)
	Check if the address is free.
uint8_t	i3c_addr_slots_next_free_find (struct i3c_addr_slots *slots, uint8_t start_addr)
	Find the next free address.
static void	i3c_addr_slots_mark_free (struct i3c_addr_slots *addr_slots, uint8_t addr)
	Mark the address as free (not used) in device list.
static void	i3c_addr_slots_mark_rsvd (struct i3c_addr_slots *addr_slots, uint8_t addr)
