Some socs have a large number of interrupts requests to service the needs of its many peripherals and subsystems. All of the interrupt lines from the subsystems are not needed at the same time, so they have to be muxed to the irq-controller appropriately. In such places a interrupt controllers are preceded by an CROSSBAR that provides flexibility in muxing the device requests to the controller inputs. This driver takes care a allocating a free irq and then configuring the crossbar IP as a part of the mpu's irqchip callbacks. crossbar_init should be called right before the irqchip_init, so that it is setup to handle the irqchip callbacks.
