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);
}
