 * Set EC_CROS_GPIO_INTERRUPTS to a space-separated list of GPIO_INT items.
 *
 * Each GPIO_INT requires three parameters:
 *   gpio_signal - The enum gpio_signal for the interrupt gpio
 *   interrupt_flags - The interrupt-related flags (e.g. GPIO_INT_EDGE_BOTH)
 *   handler - The platform/ec interrupt handler.
 *
 * Ensure that this files includes all necessary headers to declare all
 * referenced handler functions.
 *
 * For example, one could use the follow definition:
 * #define EC_CROS_GPIO_INTERRUPTS \
 *   GPIO_INT(NAMED_GPIO(h1_ec_pwr_btn_odl), GPIO_INT_EDGE_BOTH, button_print)
