Come to think of it, I'm not sure the *name* of the file documenting a binding is as important to DT maintainers as the compatible string. >> To me there's no need to link the compatible string of a given HW >> module with that of the chip name the module it is embedded into.

If not, irq-tango_v2.c is fine. If we go with the v2 naming scheme, I vote for irq-tango-v2.c for consistency with the GIC drivers. Regards.
