I posted a minimal regression fix for this a few weeks ago that we
should merge to the v3.13-rc cycle:

http://www.spinics.net/lists/netdev/msg258913.html

Care to ack that one? Then if that works for you, maybe rebase these on
that one for the upcoming merge window?

Note that for the -rc cycle we don't need these extra properties as we
can get the interrupts from the struct resource after fix
4a43d686fe336c (of/irq: Pass trigger type in IRQ resource flags)
got merged.

Tony
