And you're saying the registers are not even accissible from Linux. So based on that IMO you should not even have a device tree node for it at all. You should just have the interrupt controller driver do the muxing on request_irq() using tisci calls. If that's not true, and these mux registers are accessible from Linux, then set up proper dts node with reg entries. And have the driver deal with the firmware based on the compatible node.
