Device Tables (DT) for IP otbn and top earlgrey.
This file contains the type definitions and global functions of the otbn.
Definition in file dt_otbn.h.
| #define OPENTITAN_OTBN_HAS_MEM_SCRAMBLE 1 |
| typedef enum dt_otbn_alert dt_otbn_alert_t |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.
| typedef enum dt_otbn_clock dt_otbn_clock_t |
List of clock ports.
Clock ports are guaranteed to be numbered consecutively from 0.
| typedef enum dt_otbn_irq dt_otbn_irq_t |
List of IRQs.
IRQs are guaranteed to be numbered consecutively from 0.
| typedef enum dt_otbn_reg_block dt_otbn_reg_block_t |
List of register blocks.
Register blocks are guaranteed to start at 0 and to be consecutively numbered.
| typedef enum dt_otbn_reset dt_otbn_reset_t |
List of reset ports.
Reset ports are guaranteed to be numbered consecutively from 0.
| enum dt_otbn_alert |
| enum dt_otbn_clock |
| enum dt_otbn_irq |
| enum dt_otbn_reg_block |
| enum dt_otbn_reset |
| dt_otbn_alert_t dt_otbn_alert_from_alert_id | ( | dt_otbn_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local otbn alert type.
| dt | Instance of otbn. |
| alert | A global alert ID that belongs to this instance. |
kDtOtbnAlertCount.Note: This function assumes that the global alert ID belongs to the instance of otbn passed in parameter. In other words, it must be the case that dt_otbn_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtOtbnAlertCount.
| dt_alert_id_t dt_otbn_alert_to_alert_id | ( | dt_otbn_t | dt, |
| dt_otbn_alert_t | alert ) |
Get the alert ID of a otbn 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 otbn. |
| alert | A otbn alert. |
| dt_clock_t dt_otbn_clock | ( | dt_otbn_t | dt, |
| dt_otbn_clock_t | clk ) |
| dt_otbn_t dt_otbn_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the otbn 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 otbn, otherwise the returned value is unspecified.
| dt_instance_id_t dt_otbn_instance_id | ( | dt_otbn_t | dt | ) |
| dt_otbn_irq_t dt_otbn_irq_from_plic_id | ( | dt_otbn_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local otbn IRQ type.
| dt | Instance of otbn. |
| irq | A PLIC ID that belongs to this instance. |
kDtOtbnIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of otbn passed in parameter. In other words, it must be the case that dt_otbn_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtOtbnIrqCount.
| dt_plic_irq_id_t dt_otbn_irq_to_plic_id | ( | dt_otbn_t | dt, |
| dt_otbn_irq_t | irq ) |
| uint32_t dt_otbn_reg_block | ( | dt_otbn_t | dt, |
| dt_otbn_reg_block_t | reg_block ) |
| dt_reset_t dt_otbn_reset | ( | dt_otbn_t | dt, |
| dt_otbn_reset_t | rst ) |
