Description of instances.

Definition at line 19 of file dt_adc_ctrl.c.

Data Fields
uint32_t	base_addr[kDtAdcCtrlRegBlockCount]	Base address of each register block.
dt_clock_t	clock[kDtAdcCtrlClockCount]	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.

Macro Definition Documentation

TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({     if ((dt) < (dt_adc_ctrl_t)0 || (dt) >= kDtAdcCtrlCount)       return (default);     &adc_ctrl_desc[dt];   })

Return a pointer to the dt_adc_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.

Function Documentation

dt_adc_ctrl_alert_from_alert_id()

dt_adc_ctrl_alert_t dt_adc_ctrl_alert_from_alert_id	(	dt_adc_ctrl_t	dt,
		dt_alert_id_t	alert )

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

Parameters

dt	Instance of adc_ctrl.
alert	A global alert ID that belongs to this instance.

Returns

The adc_ctrl alert, or kDtAdcCtrlAlertCount.

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

Definition at line 117 of file dt_adc_ctrl.c.

dt_adc_ctrl_alert_to_alert_id()

dt_alert_id_t dt_adc_ctrl_alert_to_alert_id	(	dt_adc_ctrl_t	dt,
		dt_adc_ctrl_alert_t	alert )

Get the alert ID of a adc_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

dt	Instance of adc_ctrl.
alert	A adc_ctrl alert.

Returns

The Alert Handler alert ID of the alert of this instance.

Definition at line 111 of file dt_adc_ctrl.c.

dt_adc_ctrl_clock()

dt_clock_t dt_adc_ctrl_clock	(	dt_adc_ctrl_t	dt,
		dt_adc_ctrl_clock_t	clk )

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

Parameters

dt	Instance of adc_ctrl.
clk	Clock port.

Returns

Clock signal.

Definition at line 129 of file dt_adc_ctrl.c.

dt_adc_ctrl_from_instance_id()

dt_adc_ctrl_t dt_adc_ctrl_from_instance_id

(

dt_instance_id_t

inst_id

)

Get the adc_ctrl instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id

Instance ID.

Returns

A adc_ctrl instance.

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

Definition at line 67 of file dt_adc_ctrl.c.

dt_adc_ctrl_instance_id()

dt_instance_id_t dt_adc_ctrl_instance_id

(

dt_adc_ctrl_t

dt

)

Get the instance ID of an instance.

Parameters

dt	Instance of adc_ctrl.

Returns

The instance ID of that instance.

Definition at line 74 of file dt_adc_ctrl.c.

dt_adc_ctrl_irq_from_plic_id()

dt_adc_ctrl_irq_t dt_adc_ctrl_irq_from_plic_id	(	dt_adc_ctrl_t	dt,
		dt_plic_irq_id_t	irq )

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

Parameters

dt	Instance of adc_ctrl.
irq	A PLIC ID that belongs to this instance.

Returns

The adc_ctrl IRQ, or kDtAdcCtrlIrqCount.

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

Definition at line 96 of file dt_adc_ctrl.c.

dt_adc_ctrl_irq_to_plic_id()

dt_plic_irq_id_t dt_adc_ctrl_irq_to_plic_id	(	dt_adc_ctrl_t	dt,
		dt_adc_ctrl_irq_t	irq )

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

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

Parameters

dt	Instance of adc_ctrl.
irq	A adc_ctrl IRQ.

Returns

The PLIC ID of the IRQ of this instance.

Definition at line 86 of file dt_adc_ctrl.c.

dt_adc_ctrl_reg_block()

uint32_t dt_adc_ctrl_reg_block	(	dt_adc_ctrl_t	dt,
		dt_adc_ctrl_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of adc_ctrl.
reg_block	The register block requested.

Returns

The register base address of the requested block.

Definition at line 79 of file dt_adc_ctrl.c.

dt_adc_ctrl_reset()

dt_reset_t dt_adc_ctrl_reset	(	dt_adc_ctrl_t	dt,
		dt_adc_ctrl_reset_t	rst )

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

Parameters

dt	Instance of adc_ctrl.
rst	Reset port.

Returns

Reset signal.
