Rather than putting binding docs in an arch-specific directory, perhaps
put them into a device-type-specific directory, such as
bindings/interrupt-controller/brcm,bcm63xx-epic.txt?

The DT documentation should be self-contained, and not reference
anything OS-specific. In this case, you could reference
Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
for the interrupt flags.

Don't you need some reg properties in the perf and interrupt-controller
nodes so that the register address can be determined?
