| #define OPENTITAN_UART_HAS_PARITY 1 |
| typedef enum dt_uart_alert dt_uart_alert_t |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.
| typedef enum dt_uart_clock dt_uart_clock_t |
List of clock ports.
Clock ports are guaranteed to be numbered consecutively from 0.
| typedef enum dt_uart_irq dt_uart_irq_t |
List of IRQs.
IRQs are guaranteed to be numbered consecutively from 0.
| typedef enum dt_uart_periph_io dt_uart_periph_io_t |
List of peripheral I/O.
Peripheral I/O are guaranteed to be numbered consecutively from 0.
| typedef enum dt_uart_reg_block dt_uart_reg_block_t |
List of register blocks.
Register blocks are guaranteed to start at 0 and to be consecutively numbered.
| typedef enum dt_uart_reset dt_uart_reset_t |
List of reset ports.
Reset ports are guaranteed to be numbered consecutively from 0.
| enum dt_uart |
| enum dt_uart_alert |
| enum dt_uart_clock |
| enum dt_uart_irq |
List of IRQs.
IRQs are guaranteed to be numbered consecutively from 0.
| enum dt_uart_periph_io |
| enum dt_uart_reg_block |
| enum dt_uart_reset |
| dt_uart_alert_t dt_uart_alert_from_alert_id | ( | dt_uart_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local uart alert type.
| dt | Instance of uart. |
| alert | A global alert ID that belongs to this instance. |
kDtUartAlertCount.Note: This function assumes that the global alert ID belongs to the instance of uart passed in parameter. In other words, it must be the case that dt_uart_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtUartAlertCount.
| dt_alert_id_t dt_uart_alert_to_alert_id | ( | dt_uart_t | dt, |
| dt_uart_alert_t | alert ) |
Get the alert ID of a uart 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 uart. |
| alert | A uart alert. |
| dt_clock_t dt_uart_clock | ( | dt_uart_t | dt, |
| dt_uart_clock_t | clk ) |
| dt_uart_t dt_uart_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the uart 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 uart, otherwise the returned value is unspecified.
| dt_instance_id_t dt_uart_instance_id | ( | dt_uart_t | dt | ) |
| dt_uart_irq_t dt_uart_irq_from_plic_id | ( | dt_uart_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local uart IRQ type.
| dt | Instance of uart. |
| irq | A PLIC ID that belongs to this instance. |
kDtUartIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of uart passed in parameter. In other words, it must be the case that dt_uart_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtUartIrqCount.
