There is a IRQ crossbar device in the soc, which maps the irq requests from the peripherals to the mpu interrupt controller's inputs. The Peripheral irq requests are connected to only one crossbar input and the output of the crossbar is connected to only one controller's input line. The crossbar device is used to map a peripheral input to a free mpu's interrupt controller line.
