| struct dt_desc_hmac |
| Data Fields | ||
|---|---|---|
| uint32_t | base_addr[kDtHmacRegBlockCount] | Base address of each register block. |
| dt_clock_t | clock[kDtHmacClockCount] | Clock signal connected to each clock port. |
| top_darjeeling_alert_id_t | first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler. |
| top_earlgrey_alert_id_t | first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler. |
| top_darjeeling_plic_irq_id_t | first_irq |
PLIC ID of the first IRQ of this instance. This can be |
| top_earlgrey_plic_irq_id_t | first_irq |
PLIC ID of the first IRQ of this instance. This can be |
| dt_instance_id_t | inst_id | Instance ID. |
| dt_reset_t | reset[kDtHmacResetCount] | Reset signal connected to each reset port. |
| #define TRY_GET_DT | ( | dt, | |
| default ) |
Return a pointer to the dt_hmac_desc_t structure of the requested dt if it's a valid index.
Otherwise, this macro will return (i.e. exit the function) with the provided default value.
| dt_hmac_alert_t dt_hmac_alert_from_alert_id | ( | dt_hmac_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local hmac alert type.
| dt | Instance of hmac. |
| alert | A global alert ID that belongs to this instance. |
kDtHmacAlertCount.Note: This function assumes that the global alert ID belongs to the instance of hmac passed in parameter. In other words, it must be the case that dt_hmac_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtHmacAlertCount.
| dt_alert_id_t dt_hmac_alert_to_alert_id | ( | dt_hmac_t | dt, |
| dt_hmac_alert_t | alert ) |
Get the alert ID of a hmac alert for a given instance.
Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.
| dt | Instance of hmac. |
| alert | A hmac alert. |
| dt_clock_t dt_hmac_clock | ( | dt_hmac_t | dt, |
| dt_hmac_clock_t | clk ) |
| dt_hmac_t dt_hmac_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the hmac instance from an instance ID.
For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.
| inst_id | Instance ID. |
Note: This function only makes sense if the instance ID has device type hmac, otherwise the returned value is unspecified.
| dt_instance_id_t dt_hmac_instance_id | ( | dt_hmac_t | dt | ) |
| dt_hmac_irq_t dt_hmac_irq_from_plic_id | ( | dt_hmac_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local hmac IRQ type.
| dt | Instance of hmac. |
| irq | A PLIC ID that belongs to this instance. |
kDtHmacIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of hmac passed in parameter. In other words, it must be the case that dt_hmac_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtHmacIrqCount.
| dt_plic_irq_id_t dt_hmac_irq_to_plic_id | ( | dt_hmac_t | dt, |
| dt_hmac_irq_t | irq ) |
| uint32_t dt_hmac_reg_block | ( | dt_hmac_t | dt, |
| dt_hmac_reg_block_t | reg_block ) |
| dt_reset_t dt_hmac_reset | ( | dt_hmac_t | dt, |
| dt_hmac_reset_t | rst ) |
