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 | |
int | i3c_addr_slots_init (const struct device *dev) |
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) |
