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 dts file update to support the crossbar device and convert
peripheral irq numbers to crossbar number are added here.
This is a rebase of V4 series on top of 3.15-rc4
This series depends on crossbar-driver-fixes sent below

arm: dts: dra7: Add crossbar device binding

inputs
arm: dts: dra7: Add routable-irqs property for gic node
OK, assuming the bisectability issues discussed earlier on this thread
are addressed. I have tested the earlier crossbar patch series in
conjunction with this dts series with VIP capture and DSS display
running together on DRA7. Looks good with this combination of
devices. VIP is one of the modules that must have a crossbar mapping as
there is no default interrupt mapping for it, therefore VIP makes a good
test case.
So please feel free to add:

DMM doesn't get used by default since it's hwmod is missing in DRA7x's
hwmod data. I added the hwmod and tried using dmm with omapdrm, it works
fine.
So, for DSS and DMM:
