Device Tables (DT) for IP mbx and top darjeeling.
This file contains the type definitions and global functions of the mbx.
Definition in file dt_mbx.h.
| typedef enum dt_mbx_alert dt_mbx_alert_t |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.
| typedef enum dt_mbx_clock dt_mbx_clock_t |
List of clock ports.
Clock ports are guaranteed to be numbered consecutively from 0.
| typedef enum dt_mbx_irq dt_mbx_irq_t |
List of IRQs.
IRQs are guaranteed to be numbered consecutively from 0.
| typedef enum dt_mbx_reg_block dt_mbx_reg_block_t |
List of register blocks.
Register blocks are guaranteed to start at 0 and to be consecutively numbered.
| typedef enum dt_mbx_reset dt_mbx_reset_t |
List of reset ports.
Reset ports are guaranteed to be numbered consecutively from 0.
| enum dt_mbx |
| enum dt_mbx_alert |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.
| enum dt_mbx_clock |
| enum dt_mbx_irq |
| enum dt_mbx_reg_block |
| enum dt_mbx_reset |
| dt_mbx_alert_t dt_mbx_alert_from_alert_id | ( | dt_mbx_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local mbx alert type.
| dt | Instance of mbx. |
| alert | A global alert ID that belongs to this instance. |
kDtMbxAlertCount.Note: This function assumes that the global alert ID belongs to the instance of mbx passed in parameter. In other words, it must be the case that dt_mbx_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtMbxAlertCount.
| dt_alert_id_t dt_mbx_alert_to_alert_id | ( | dt_mbx_t | dt, |
| dt_mbx_alert_t | alert ) |
Get the alert ID of a mbx 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 mbx. |
| alert | A mbx alert. |
| dt_clock_t dt_mbx_clock | ( | dt_mbx_t | dt, |
| dt_mbx_clock_t | clk ) |
| dt_mbx_t dt_mbx_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the mbx 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 mbx, otherwise the returned value is unspecified.
| dt_instance_id_t dt_mbx_instance_id | ( | dt_mbx_t | dt | ) |
| dt_mbx_irq_t dt_mbx_irq_from_plic_id | ( | dt_mbx_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local mbx IRQ type.
| dt | Instance of mbx. |
| irq | A PLIC ID that belongs to this instance. |
kDtMbxIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of mbx passed in parameter. In other words, it must be the case that dt_mbx_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtMbxIrqCount.
| dt_plic_irq_id_t dt_mbx_irq_to_plic_id | ( | dt_mbx_t | dt, |
| dt_mbx_irq_t | irq ) |
| uint32_t dt_mbx_reg_block | ( | dt_mbx_t | dt, |
| dt_mbx_reg_block_t | reg_block ) |
| dt_reset_t dt_mbx_reset | ( | dt_mbx_t | dt, |
| dt_mbx_reset_t | rst ) |
