* Name: s32k1xx_gpiosetevent
*
* Description:
* Sets/clears GPIO based event and interrupt triggers.
*
* Input Parameters:
* - pinset: gpio pin configuration
* - rising/falling edge: enables
* - event: generate event when set
* - func: when non-NULL, generate interrupt
* - arg: Argument passed to the interrupt callback
*
* Returned Value:
* Zero (OK) on success; a negated errno value on failure indicating the
* nature of the failure.
