Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({ if ((dt) < (dt_pwrmgr_t)0 || (dt) >= kDtPwrmgrCount) return (default); &pwrmgr_desc[dt]; })

Return a pointer to the dt_pwrmgr_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_pwrmgr_alert_from_alert_id()

dt_pwrmgr_alert_t dt_pwrmgr_alert_from_alert_id	(	dt_pwrmgr_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns: The pwrmgr alert, or kDtPwrmgrAlertCount.

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

Definition at line 181 of file dt_pwrmgr.c.

◆ dt_pwrmgr_alert_to_alert_id()

dt_alert_id_t dt_pwrmgr_alert_to_alert_id	(	dt_pwrmgr_t	dt,
		dt_pwrmgr_alert_t	alert )

Get the alert ID of a pwrmgr 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 pwrmgr.
alert	A pwrmgr alert.

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

Definition at line 175 of file dt_pwrmgr.c.

◆ dt_pwrmgr_clock()

dt_clock_t dt_pwrmgr_clock	(	dt_pwrmgr_t	dt,
		dt_pwrmgr_clock_t	clk )

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

Parameters

dt	Instance of pwrmgr.
clk	Clock port.

Returns: Clock signal.

Definition at line 193 of file dt_pwrmgr.c.

◆ dt_pwrmgr_from_instance_id()

dt_pwrmgr_t dt_pwrmgr_from_instance_id ( dt_instance_id_t inst_id )

Get the pwrmgr instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A pwrmgr instance.

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

Definition at line 117 of file dt_pwrmgr.c.

◆ dt_pwrmgr_instance_id()

dt_instance_id_t dt_pwrmgr_instance_id ( dt_pwrmgr_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of pwrmgr.

Returns: The instance ID of that instance.

Definition at line 124 of file dt_pwrmgr.c.

◆ dt_pwrmgr_irq_from_plic_id()

dt_pwrmgr_irq_t dt_pwrmgr_irq_from_plic_id	(	dt_pwrmgr_t	dt,
		dt_plic_irq_id_t	irq )

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

Parameters

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

Returns: The pwrmgr IRQ, or kDtPwrmgrIrqCount.

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

Definition at line 160 of file dt_pwrmgr.c.

◆ dt_pwrmgr_irq_to_plic_id()

dt_plic_irq_id_t dt_pwrmgr_irq_to_plic_id	(	dt_pwrmgr_t	dt,
		dt_pwrmgr_irq_t	irq )

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

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

Parameters

dt	Instance of pwrmgr.
irq	A pwrmgr IRQ.

Returns: The PLIC ID of the IRQ of this instance.

Definition at line 150 of file dt_pwrmgr.c.
