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.

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 at ti.com>

Applied this series on top of
  git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git
