)

#include <input_touch.h>

Value:

{                                                               \

        .inverted_x = DT_PROP(node_id, inverted_x),             \
        .inverted_y = DT_PROP(node_id, inverted_y),             \
        .swapped_x_y = DT_PROP(node_id, swapped_x_y),           \
        .output_width = INPUT_TOUCH_OUTPUT_DIM(node_id, width, output_width),   \
        .output_height = INPUT_TOUCH_OUTPUT_DIM(node_id, height, output_height),        \
}

Initialize common touchscreen config from devicetree.

Parameters

node_id

The devicetree node identifier.

INPUT_TOUCH_DT_INST_COMMON_CONFIG_INIT

#define INPUT_TOUCH_DT_INST_COMMON_CONFIG_INIT

(

inst

)

#include <input_touch.h>

Value:

INPUT_TOUCH_DT_COMMON_CONFIG_INIT(DT_DRV_INST(inst))

Initialize common touchscreen config from devicetree instance.

Parameters

inst

Instance.

INPUT_TOUCH_OUTPUT_DIM

#define INPUT_TOUCH_OUTPUT_DIM	(		node_id,
			dim,
			prop )

#include <input_touch.h>

Value:

COND_CODE_1(DT_NODE_HAS_PROP(node_id, display),                 \
        (DT_PROP(DT_PHANDLE(node_id, display), dim)),           \
        (DT_PROP_OR(node_id, prop, 0)))

Select an output dimension from the display phandle, else the node's own property.

Prefers the width/height of the node referenced by the display phandle; falls back to the node's own output-width / output-height when display is not set, and to 0 when neither is present, which disables scaling.

Parameters

node_id	The devicetree node identifier.
dim	The display-controller dimension property (width or height).
prop	The touchscreen fallback property (output_width or output_height).

INPUT_TOUCH_STRUCT_CHECK

#define INPUT_TOUCH_STRUCT_CHECK

(

config

)

#include <input_touch.h>

Value:

BUILD_ASSERT(offsetof(config, common) == 0, \
             "struct input_touchscreen_common_config must be placed first");

Validate the offset of the common config structure.

Parameters

config

Name of the config structure.

#include <input_touch.h>

Common utility for reporting touchscreen position events.
