Macro Definition Documentation

◆ TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({ if ((dt) < (dt_pwrmgr_t)0 || (int)(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.

Definition at line 93 of file pwrmgr.c.

Function Documentation

◆ 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 141 of file 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 95 of file 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 102 of file 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 124 of file 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 114 of file pwrmgr.c.

◆ dt_pwrmgr_reg_block()

uint32_t dt_pwrmgr_reg_block	(	dt_pwrmgr_t	dt,
		dt_pwrmgr_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of pwrmgr.
reg_block	The register block requested.

Returns: The register base address of the requested block.

Definition at line 107 of file pwrmgr.c.

◆ dt_pwrmgr_reset()

dt_reset_t dt_pwrmgr_reset	(	dt_pwrmgr_t	dt,
		dt_pwrmgr_reset_t	rst )

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

Parameters

dt	Instance of pwrmgr.
rst	Reset port.

Returns: Reset signal.

Definition at line 148 of file pwrmgr.c.

◆ dt_pwrmgr_reset_request_src()

dt_pwrmgr_reset_req_src_t dt_pwrmgr_reset_request_src	(	dt_pwrmgr_t	dt,
		size_t	idx )

Get the description of a reset request.

The reset requests are ordered as they appear in the registers.

Parameters

dt	Instance of pwrmgr.
idx	Index of the reset request source, between 0 and `dt_pwrmgr_reset_request_src_count(dt)-1`.

Returns: Description of the reset.

Definition at line 173 of file pwrmgr.c.

◆ dt_pwrmgr_reset_request_src_count()

size_t dt_pwrmgr_reset_request_src_count ( dt_pwrmgr_t dt )

Get the number of peripheral reset requests.

Parameters

dt	Instance of pwrmgr.

Returns: Number of reset requests.

Definition at line 169 of file pwrmgr.c.

◆ dt_pwrmgr_wakeup_src()

dt_pwrmgr_wakeup_src_t dt_pwrmgr_wakeup_src	(	dt_pwrmgr_t	dt,
		size_t	idx )

Get the description of a wakeup source.

The wakeup sources are ordered as they appear in the registers.

Parameters

dt	Instance of pwrmgr.
idx	Index of the wakeup source, between 0 and `dt_pwrmgr_wakeup_src_count(dt)-1`.

Returns: Description of the source.

Definition at line 164 of file pwrmgr.c.

◆ dt_pwrmgr_wakeup_src_count()

size_t dt_pwrmgr_wakeup_src_count ( dt_pwrmgr_t dt )

Parameters

dt	Instance of pwrmgr.

Returns: Number of wakeup sources.
