Hi Andrew,
I have a WARN_ON at system startup time of the Cubox (Marvell Dove).
Sorry for I don't know enough about the IRQ subsystem to fix it.
irq: no irq domain found for /mbus/internal-regs/pmu-interrupt-ctrl at d0050 !

Hi Jean-Francois
The DT node made it into -rc1, but the driver itself was forgotten by
the IRQ maintainer. It will hopefully appear in -rc2.

Unfortunately, this didn't happen. I've posted a patch to revert adding
the DT node for v3.14. It'll be re-added in conjunction with the driver
code. Hopefully for v3.15.

Please test and let me know if that fixes the WARN_ON.
thx,
Jason.
