The gpio driver (gpio-msc313.c) sets it during probe: gpioirqchip = &gpiochip->irq; gpioirqchip->chip = &msc313_gpio_irqchip; gpioirqchip->fwnode = of_node_to_fwnode(dev->of_node); gpioirqchip->parent_domain = parent_domain; gpioirqchip->child_to_parent_hwirq = match_data->child_to_parent_hwirq; gpioirqchip->populate_parent_alloc_arg = match_data->populate_parent_fwspec; gpioirqchip->handler = handle_bad_irq; gpioirqchip->default_type = IRQ_TYPE_NONE; Cheers, Daniel
