	Support for the TI crossbar used on the DRA7 family of chips is implemented as an ugly hack on the side of the GIC. Converting it to stacked domains makes it slightly more palatable, as it results in a cleanup. Unfortunately, as the DT bindings failed to acknowledge the fact that this is actually yet another interrupt controller (the third, actually), we have yet another breakage. Oh well.

2014-02-05	DRIVERS: IRQCHIP: CROSSBAR: Add support for Crossbar IP	Sricharan R	1	-0/+11
	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.
