Description of instances.

| Data Fields | ||
|---|---|---|
| uint32_t | base_addr[kDtSpiDeviceRegBlockCount] | Base address of each register block. |
| dt_clock_t | clock[kDtSpiDeviceClockCount] | 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 |
| top_englishbreakfast_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_periph_io_t | periph_io[kDtSpiDevicePeriphIoCount] | Description of each peripheral I/O. |
| dt_reset_t | reset[kDtSpiDeviceResetCount] | Reset signal connected to each reset port. |
| #define TRY_GET_DT | ( | dt, | |
| default ) |
Return a pointer to the dt_spi_device_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_spi_device_alert_t dt_spi_device_alert_from_alert_id | ( | dt_spi_device_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local spi_device alert type.
| dt | Instance of spi_device. |
| alert | A global alert ID that belongs to this instance. |
kDtSpiDeviceAlertCount.Note: This function assumes that the global alert ID belongs to the instance of spi_device passed in parameter. In other words, it must be the case that dt_spi_device_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtSpiDeviceAlertCount.

| dt_alert_id_t dt_spi_device_alert_to_alert_id | ( | dt_spi_device_t | dt, |
| dt_spi_device_alert_t | alert ) |
Get the alert ID of a spi_device 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 spi_device. |
| alert | A spi_device alert. |
Definition at line 168 of file dt_spi_device.c.
Get the clock signal connected to a clock port of an instance.
| dt | Instance of spi_device. |
| clk | Clock port. |
Definition at line 192 of file dt_spi_device.c.
| dt_spi_device_t dt_spi_device_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the spi_device 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 spi_device, otherwise the returned value is unspecified.
Definition at line 124 of file dt_spi_device.c.
| dt_instance_id_t dt_spi_device_instance_id | ( | dt_spi_device_t | dt | ) |
Get the instance ID of an instance.
| dt | Instance of spi_device. |
Definition at line 131 of file dt_spi_device.c.
| dt_spi_device_irq_t dt_spi_device_irq_from_plic_id | ( | dt_spi_device_t | dt, |
| dt_plic_irq_id_t | irq ) |
Convert a global IRQ ID to a local spi_device IRQ type.
| dt | Instance of spi_device. |
| irq | A PLIC ID that belongs to this instance. |
kDtSpiDeviceIrqCount.Note: This function assumes that the PLIC ID belongs to the instance of spi_device passed in parameter. In other words, it must be the case that dt_spi_device_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtSpiDeviceIrqCount.

| dt_plic_irq_id_t dt_spi_device_irq_to_plic_id | ( | dt_spi_device_t | dt, |
| dt_spi_device_irq_t | irq ) |
Get the PLIC ID of a spi_device IRQ for a given instance.
If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.
| dt | Instance of spi_device. |
| irq | A spi_device IRQ. |
Definition at line 143 of file dt_spi_device.c.
Get the peripheral I/O description of an instance.
| dt | Instance of spi_device. |
| sig | Requested peripheral I/O. |
Definition at line 185 of file dt_spi_device.c.
| uint32_t dt_spi_device_reg_block | ( | dt_spi_device_t | dt, |
| dt_spi_device_reg_block_t | reg_block ) |
Get the register base address of an instance.
| dt | Instance of spi_device. |
| reg_block | The register block requested. |
Definition at line 136 of file dt_spi_device.c.
Get the reset signal connected to a reset port of an instance.
| dt | Instance of spi_device. |
| rst | Reset port. |
