Data Structure Documentation

◆ dt_desc_flash_ctrl

struct dt_desc_flash_ctrl

Description of instances.

Definition at line 19 of file dt_flash_ctrl.c.

Data Fields
uint32_t base_addr[kDtFlashCtrlRegBlockCount] Base address of each register block.
dt_clock_t clock[kDtFlashCtrlClockCount] Clock signal connected to each clock port.
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_earlgrey_plic_irq_id_t first_irq PLIC ID of the first IRQ of this instance.

This can be kDtPlicIrqIdNone if the block is not connected to the PLIC.

top_englishbreakfast_plic_irq_id_t first_irq PLIC ID of the first IRQ of this instance.

This can be kDtPlicIrqIdNone if the block is not connected to the PLIC.

dt_instance_id_t inst_id Instance ID.
dt_periph_io_t periph_io[kDtFlashCtrlPeriphIoCount] Description of each peripheral I/O.
dt_reset_t reset[kDtFlashCtrlResetCount] Reset signal connected to each reset port.

Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT ( dt,
default )
Value:
({ if ((dt) < (dt_flash_ctrl_t)0 || (dt) >= kDtFlashCtrlCount) return (default); &flash_ctrl_desc[dt]; })

Return a pointer to the dt_flash_ctrl_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.

Definition at line 102 of file dt_flash_ctrl.c.

Function Documentation

◆ dt_flash_ctrl_alert_from_alert_id()

dt_flash_ctrl_alert_t dt_flash_ctrl_alert_from_alert_id ( dt_flash_ctrl_t dt,
dt_alert_id_t alert )

Convert a global alert ID to a local flash_ctrl alert type.

Parameters
dtInstance of flash_ctrl.
alertA global alert ID that belongs to this instance.
Returns
The flash_ctrl alert, or kDtFlashCtrlAlertCount.

Note: This function assumes that the global alert ID belongs to the instance of flash_ctrl passed in parameter. In other words, it must be the case that dt_flash_ctrl_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtFlashCtrlAlertCount.

Definition at line 154 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_alert_to_alert_id()

dt_alert_id_t dt_flash_ctrl_alert_to_alert_id ( dt_flash_ctrl_t dt,
dt_flash_ctrl_alert_t alert )

Get the alert ID of a flash_ctrl 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.

Parameters
dtInstance of flash_ctrl.
alertA flash_ctrl alert.
Returns
The Alert Handler alert ID of the alert of this instance.

Definition at line 148 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_clock()

Get the clock signal connected to a clock port of an instance.

Parameters
dtInstance of flash_ctrl.
clkClock port.
Returns
Clock signal.

Definition at line 172 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_from_instance_id()

dt_flash_ctrl_t dt_flash_ctrl_from_instance_id ( dt_instance_id_t inst_id)

Get the flash_ctrl instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters
inst_idInstance ID.
Returns
A flash_ctrl instance.

Note: This function only makes sense if the instance ID has device type flash_ctrl, otherwise the returned value is unspecified.

Definition at line 104 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_instance_id()

dt_instance_id_t dt_flash_ctrl_instance_id ( dt_flash_ctrl_t dt)

Get the instance ID of an instance.

Parameters
dtInstance of flash_ctrl.
Returns
The instance ID of that instance.

Definition at line 111 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_irq_from_plic_id()

dt_flash_ctrl_irq_t dt_flash_ctrl_irq_from_plic_id ( dt_flash_ctrl_t dt,
dt_plic_irq_id_t irq )

Convert a global IRQ ID to a local flash_ctrl IRQ type.

Parameters
dtInstance of flash_ctrl.
irqA PLIC ID that belongs to this instance.
Returns
The flash_ctrl IRQ, or kDtFlashCtrlIrqCount.

Note: This function assumes that the PLIC ID belongs to the instance of flash_ctrl passed in parameter. In other words, it must be the case that dt_flash_ctrl_instance_id(dt) == dt_plic_id_to_instance_id(irq). Otherwise, this function will return kDtFlashCtrlIrqCount.

Definition at line 133 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_irq_to_plic_id()

dt_plic_irq_id_t dt_flash_ctrl_irq_to_plic_id ( dt_flash_ctrl_t dt,
dt_flash_ctrl_irq_t irq )

Get the PLIC ID of a flash_ctrl IRQ for a given instance.

If the instance is not connected to the PLIC, this function will return kDtPlicIrqIdNone.

Parameters
dtInstance of flash_ctrl.
irqA flash_ctrl IRQ.
Returns
The PLIC ID of the IRQ of this instance.

Definition at line 123 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_periph_io()

Get the peripheral I/O description of an instance.

Parameters
dtInstance of flash_ctrl.
sigRequested peripheral I/O.
Returns
Description of the requested peripheral I/O for this instance.

Definition at line 165 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_reg_block()

Get the register base address of an instance.

Parameters
dtInstance of flash_ctrl.
reg_blockThe register block requested.
Returns
The register base address of the requested block.

Definition at line 116 of file dt_flash_ctrl.c.

◆ dt_flash_ctrl_reset()

Get the reset signal connected to a reset port of an instance.

Parameters
dtInstance of flash_ctrl.
rstReset port.
Returns
Reset signal.
