Some socs have a large number of interrupts requests to service
the needs of its many peripherals and subsystems. All of the interrupt
requests lines from the subsystems are not needed at the same
time, so they have to be muxed to the controllers appropriately.
In such places a interrupt controllers are preceded by an
IRQ CROSSBAR that provides flexibility in muxing the device interrupt
requests to the controller inputs.
The driver support for the same was added here.
http://marc.info/?l=linux-omap&m=138443167321614&w=2
The dts file update to support the crossbar device and convert
peripheral irq numbers to crossbar number are added here.
This series was originally a part of the series [1] and now split
to keep the DTS updates separately as per comments from
Santosh Shilimkar <santosh.shilimkar@ti.com>
Applied this series on top of

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.

Instead they rely on the crossbar irqchip to allocate and map a free interrupt line to its crossbar input. So replacing all the peripheral interrupt numbers with its fixed crossbar input lines.
