Sorry, but this isn't much of an interrupt controller driver. A modern interrupt controller driver is firmware-driven (DT or ACPI, pick your poison), uses irq domains, and uses the irqchip API. This is just a another variant of the board-file theme, which has nothing to do with the irqchip subsystem. M. -- Without deviation from the norm, progress is not possible.
