Function Documentation

◆ dt_sysrst_ctrl_alert_from_alert_id()

dt_sysrst_ctrl_alert_t dt_sysrst_ctrl_alert_from_alert_id	(	dt_sysrst_ctrl_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns: The sysrst_ctrl alert, or kDtSysrstCtrlAlertCount.

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

Definition at line 232 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_alert_to_alert_id()

dt_alert_id_t dt_sysrst_ctrl_alert_to_alert_id	(	dt_sysrst_ctrl_t	dt,
		dt_sysrst_ctrl_alert_t	alert )

Get the alert ID of a sysrst_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 sysrst_ctrl.
alert	A sysrst_ctrl alert.

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

Definition at line 226 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_clock()

dt_clock_t dt_sysrst_ctrl_clock	(	dt_sysrst_ctrl_t	dt,
		dt_sysrst_ctrl_clock_t	clk )

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

Parameters

dt	Instance of sysrst_ctrl.
clk	Clock port.

Returns: Clock signal.

Definition at line 250 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_from_instance_id()

dt_sysrst_ctrl_t dt_sysrst_ctrl_from_instance_id ( dt_instance_id_t inst_id )

Get the sysrst_ctrl instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id Instance ID.

Returns: A sysrst_ctrl instance.

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

Definition at line 182 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_instance_id()

dt_instance_id_t dt_sysrst_ctrl_instance_id ( dt_sysrst_ctrl_t dt )

Get the instance ID of an instance.

Parameters

dt	Instance of sysrst_ctrl.

Returns: The instance ID of that instance.

Definition at line 189 of file dt_sysrst_ctrl.c.

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

Parameters

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

Returns: The sysrst_ctrl IRQ, or kDtSysrstCtrlIrqCount.

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

Definition at line 211 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_irq_to_plic_id()

dt_plic_irq_id_t dt_sysrst_ctrl_irq_to_plic_id	(	dt_sysrst_ctrl_t	dt,
		dt_sysrst_ctrl_irq_t	irq )

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

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

Parameters

dt	Instance of sysrst_ctrl.
irq	A sysrst_ctrl IRQ.

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

Definition at line 201 of file dt_sysrst_ctrl.c.

		dt_sysrst_ctrl_periph_io_t	sig )

Get the peripheral I/O description of an instance.

Parameters

dt	Instance of sysrst_ctrl.
sig	Requested peripheral I/O.

Returns: Description of the requested peripheral I/O for this instance.

Definition at line 243 of file dt_sysrst_ctrl.c.

		dt_sysrst_ctrl_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of sysrst_ctrl.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 194 of file dt_sysrst_ctrl.c.

◆ dt_sysrst_ctrl_reset()

dt_reset_t dt_sysrst_ctrl_reset	(	dt_sysrst_ctrl_t	dt,
		dt_sysrst_ctrl_reset_t	rst )

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

Parameters

dt	Instance of sysrst_ctrl.
rst	Reset port.

Returns: Reset signal.
