If a driver implements .alloc() hook, irq_domain_check_hierarchy() sets IRQ_DOMAIN_FLAG_HIERARCHY flag. If you see kernel/irq/irqdomain.c, alloc/map is selected by irq_domain_is_hierarchy(). -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
