Typedef Documentation

nxp_gint_callback_t

typedef void(* nxp_gint_callback_t) (const struct device *dev, void *user_data)

GINT callback function type.

Parameters

dev	GINT device
user_data	User defined data

Enumeration Type Documentation

nxp_gint_combination_type

enum nxp_gint_combination_type

GINT combination logic.

Enumerator
NXP_GINT_COMB_OR	OR logic - any enabled pin triggers interrupt.
NXP_GINT_COMB_AND	AND logic - all enabled pins must trigger interrupt.

nxp_gint_polarity_type

enum nxp_gint_polarity_type

GINT pin polarity.

Enumerator
NXP_GINT_POL_LOW	Active LOW.
NXP_GINT_POL_HIGH	Active HIGH.

nxp_gint_trigger_type

enum nxp_gint_trigger_type

GINT trigger types.

Enumerator
NXP_GINT_TRIG_EDGE	Edge triggered.
NXP_GINT_TRIG_LEVEL	Level triggered.
