I am thinking of something like this. Would there be any issue in
setting the type to IRQ_TYPE_SENSE_MASK instead of any one particular
type?

---8<-----
static int gpiochip_to_irq(struct gpio_chip *chip, unsigned offset)
{
#ifdef CONFIG_OF_GPIO
       struct irq_fwspec fwspec;

       if (chip->of_node) {
              fwspec.fwnode = of_node_to_fwnode(chip->of_node);
              fwspec.param[0] = offset;
              fwspec.param[1] = IRQ_TYPE_SENSE_MASK;
              fwspec.param_count = 2;
              return irq_create_fwspec_mapping(&fwspec);
       }
#endif

       if (!gpiochip_irqchip_irq_valid(chip, offset))
               return -ENXIO;

       return irq_create_mapping(chip->irq.domain, offset);
}
