| typedef enum dt_gpio_alert dt_gpio_alert_t |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.

List of clock ports.
Clock ports are guaranteed to be numbered consecutively from 0.

List of IRQs.
IRQs are guaranteed to be numbered consecutively from 0.

List of peripheral I/O.
Peripheral I/O are guaranteed to be numbered consecutively from 0.
| typedef enum dt_gpio_reg_block dt_gpio_reg_block_t |
List of register blocks.
Register blocks are guaranteed to start at 0 and to be consecutively numbered.
| typedef enum dt_gpio_reset dt_gpio_reset_t |

| enum dt_gpio_reset |
| dt_gpio_alert_t dt_gpio_alert_from_alert_id | ( | dt_gpio_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local gpio alert type.
| dt | Instance of gpio. |
| alert | A global alert ID that belongs to this instance. |
kDtGpioAlertCount.Note: This function assumes that the global alert ID belongs to the instance of gpio passed in parameter. In other words, it must be the case that dt_gpio_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtGpioAlertCount.
| dt_alert_id_t dt_gpio_alert_to_alert_id | ( | dt_gpio_t | dt, |
| dt_gpio_alert_t | alert ) |
Get the alert ID of a gpio 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 gpio. |
| alert | A gpio alert. |
| dt_clock_t dt_gpio_clock | ( | dt_gpio_t | dt, |
| dt_gpio_clock_t | clk ) |
| dt_gpio_t dt_gpio_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the gpio 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 gpio, otherwise the returned value is unspecified.
| dt_instance_id_t dt_gpio_instance_id | ( | dt_gpio_t | dt | ) |
| dt_gpio_irq_t dt_gpio_irq_from_plic_id | ( | dt_gpio_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local gpio IRQ type.
| dt | Instance of gpio. |
| irq | A PLIC ID that belongs to this instance. |
kDtGpioIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of gpio passed in parameter. In other words, it must be the case that dt_gpio_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtGpioIrqCount.
