I think this is the right way to go, but would ideally like some feedback from the irqchip maintainers. Have you looked at drivers/irqchip/irq-crossbar.c for inspiration? Also read Documentation/devicetree/bindings/arm/omap/crossbar.txt It uses an hierarchical domain for a similar cross-connection usecase. Under any circumstances I think decoupling the IRQ multiplexer and dealing with it in separate is easier for maintainance and also for the irq maintainers to review.
