-EINVAL	If the specific port_id and pin combination has no interrupt enabled

intc_xmc4xxx_gpio_enable_interrupt()

int intc_xmc4xxx_gpio_enable_interrupt	(	int	port_id,
		int	pin,
		enum gpio_int_mode	mode,
		enum gpio_int_trig	trig,
		void(*	fn )(const struct device *, int),
		void *	user_data )

Enable interrupt for specific port_id and pin combination.

Parameters

port_id	Port index
pin	pin Pin the port
mode	Level or edge interrupt
trig	Trigger edge type (falling, rising or both)
fn	Callback function
user_data	Parameter to the interrupt callback

Return values

0	On success
-ENOTSUP	If the specific port_id/pin combination is not supported or not defined in the dts
-EBUSY	If the interrupt line is already used by a different port_id/pin
-EINVAL	If the trigger combination is invalid
