What you need to have is 1) expand fwnode_irq_get() to support ACPI GPIO IRQ resources. 2) provide a simple version of the fwnode_irq_get_by_name() like if (is_of_node()) return of_...(); return acpi_dev_gpio_irq_get_by(); 3) establish understanding about naming for ACPI and 4) extend fwnode_irq_get_by_name() by it if (is_of_node()) return of_...(); ret = acpi_irq_get_by_name(); if (ret > 0) return ret; return acpi_dev_gpio_irq_get_by(); As I mentioned, items 1 and 2 are easy to achieve with currently existing APIs. -- With Best Regards, Andy Shevchenko
