The gpio-mpc8xxx driver requires IRQ domains but can be built without them, resulting on a failure to build certain randconfigs on ARM: drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_to_irq': drivers/gpio/gpio-mpc8xxx.c:92:10: error: implicit declaration of function 'irq_create_mapping' [-Werror=implicit-function-declaration] return irq_create_mapping(mpc8xxx_gc->irq, offset); This selects IRQ_DOMAIN from the driver to ensure we can build it.
