I've done some tests on my Kirkwood Openblocks A6 using the latest
branch orion-irqchip-for-v3.11-v4. Everything works fine so:

Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>

For patches 3 to 6 I'm wondering if there's any reason why the irqchip and
clocksource changes are not separated. I'm probably being too picky but,
unless you have a good reason for having them together,
I think they should go separated, i.e. patches for irqchip on one side,
and patches for clocksource on the other.

Aside from that, the series looks good. Nice job!

Thanks,
