struct dt_desc_soc_dbg_ctrl

Description of instances.

Definition at line 19 of file dt_soc_dbg_ctrl.c.

Data Fields
uint32_t	base_addr[kDtSocDbgCtrlRegBlockCount]	Base address of each register block.
dt_clock_t	clock[kDtSocDbgCtrlClockCount]	Clock signal connected to each clock port.
top_darjeeling_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.
dt_instance_id_t	inst_id	Instance ID.
dt_reset_t	reset[kDtSocDbgCtrlResetCount]	Reset signal connected to each reset port.

Macro Definition Documentation

TRY_GET_DT

#define TRY_GET_DT	(		dt,
			default )

Value:

({     if ((dt) < (dt_soc_dbg_ctrl_t)0 || (dt) >= kDtSocDbgCtrlCount)       return (default);     &soc_dbg_ctrl_desc[dt];   })

Return a pointer to the dt_soc_dbg_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_soc_dbg_ctrl_alert_from_alert_id()

dt_soc_dbg_ctrl_alert_t dt_soc_dbg_ctrl_alert_from_alert_id	(	dt_soc_dbg_ctrl_t	dt,
		dt_alert_id_t	alert )

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

Parameters

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

Returns

The soc_dbg_ctrl alert, or kDtSocDbgCtrlAlertCount.

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

Definition at line 85 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_alert_to_alert_id()

dt_alert_id_t dt_soc_dbg_ctrl_alert_to_alert_id	(	dt_soc_dbg_ctrl_t	dt,
		dt_soc_dbg_ctrl_alert_t	alert )

Get the alert ID of a soc_dbg_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 soc_dbg_ctrl.
alert	A soc_dbg_ctrl alert.

Returns

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

Definition at line 79 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_clock()

dt_clock_t dt_soc_dbg_ctrl_clock	(	dt_soc_dbg_ctrl_t	dt,
		dt_soc_dbg_ctrl_clock_t	clk )

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

Parameters

dt	Instance of soc_dbg_ctrl.
clk	Clock port.

Returns

Clock signal.

Definition at line 97 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_from_instance_id()

dt_soc_dbg_ctrl_t dt_soc_dbg_ctrl_from_instance_id

(

dt_instance_id_t

inst_id

)

Get the soc_dbg_ctrl instance from an instance ID.

For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.

Parameters

inst_id

Instance ID.

Returns

A soc_dbg_ctrl instance.

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

Definition at line 59 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_instance_id()

dt_instance_id_t dt_soc_dbg_ctrl_instance_id

(

dt_soc_dbg_ctrl_t

dt

)

Get the instance ID of an instance.

Parameters

dt	Instance of soc_dbg_ctrl.

Returns

The instance ID of that instance.

Definition at line 66 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_reg_block()

uint32_t dt_soc_dbg_ctrl_reg_block	(	dt_soc_dbg_ctrl_t	dt,
		dt_soc_dbg_ctrl_reg_block_t	reg_block )

Get the register base address of an instance.

Parameters

dt	Instance of soc_dbg_ctrl.
reg_block	The register block requested.

Returns

The register base address of the requested block.

Definition at line 71 of file dt_soc_dbg_ctrl.c.

dt_soc_dbg_ctrl_reset()

dt_reset_t dt_soc_dbg_ctrl_reset	(	dt_soc_dbg_ctrl_t	dt,
		dt_soc_dbg_ctrl_reset_t	rst )

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

Parameters

dt	Instance of soc_dbg_ctrl.
rst	Reset port.

Returns

Reset signal.
