DT_PHA_BY_NAME_OR(node_id, pwms, name, flags, 0)

DT_PHA_BY_NAME_OR

#define DT_PHA_BY_NAME_OR(node_id, pha, name, cell, default_value)

Like DT_PHA_BY_NAME(), but with a fallback to default_value.

Definition devicetree.h:1655

Get a PWM specifier's flags cell value by name.

This macro expects PWM specifiers with cells named "flags". If there is no "flags" cell in the PWM specifier, zero is returned. Refer to the node's binding to check specifier cell names if necessary.

This is equivalent to DT_PWMS_CELL_BY_NAME(node_id, name, flags) if there is a flags cell, but expands to zero if there is none.

Parameters

node_id	node identifier for a node with a pwms property
name	lowercase-and-underscores name of a pwms element as defined by the node's pwm-names property

Returns: the flags cell value in the specifier at the named element, or zero if there is none

◆ DT_PWMS_PERIOD

#define DT_PWMS_PERIOD ( node_id )

#include <zephyr/devicetree/pwms.h>

Value:

DT_PWMS_PERIOD_BY_IDX(node_id, 0)

DT_PWMS_PERIOD_BY_IDX

#define DT_PWMS_PERIOD_BY_IDX(node_id, idx)

Get PWM specifier's period cell value at an index.

Definition pwms.h:248

Equivalent to DT_PWMS_PERIOD_BY_IDX(node_id, 0)

Parameters

node_id node identifier for a node with a pwms property

Returns: the period cell value at index 0

See also: DT_PWMS_PERIOD_BY_IDX()

◆ DT_PWMS_PERIOD_BY_IDX

#define DT_PWMS_PERIOD_BY_IDX	(		node_id,
			idx )

#include <zephyr/devicetree/pwms.h>

Value:

DT_PWMS_CELL_BY_IDX(node_id, idx, period)

Get PWM specifier's period cell value at an index.

This macro only works for PWM specifiers with cells named "period". Refer to the node's binding to check if necessary.

This is equivalent to DT_PWMS_CELL_BY_IDX(node_id, idx, period).

Parameters

node_id	node identifier for a node with a pwms property
idx	logical index into pwms property

Returns: the period cell value at index "idx"

See also: DT_PWMS_CELL_BY_IDX()

◆ DT_PWMS_PERIOD_BY_NAME

#define DT_PWMS_PERIOD_BY_NAME	(		node_id,
			name )

#include <zephyr/devicetree/pwms.h>

Value:

DT_PWMS_CELL_BY_NAME(node_id, name, period)

Get a PWM specifier's period cell value by name.

This macro only works for PWM specifiers with cells named "period". Refer to the node's binding to check if necessary.

This is equivalent to DT_PWMS_CELL_BY_NAME(node_id, name, period).

Parameters

node_id	node identifier for a node with a pwms property
name	lowercase-and-underscores name of a pwms element as defined by the node's pwm-names property

Returns: the period cell value in the specifier at the named element
