Re: [GIT PULL] at91: irqdomain and device tree for AIC and GPIO

Hi,

Hi,

Hold on with this pull request:
- I can now base the similar one on top of the "cleanup2" branch
- the irqdomain/next is now considered stable so I can
  merge it beforehand
- I can add some more material to it (still related to 
  AT91 the Device Tree conversion)

Thanks, best regards,

This series adds irqdomain and device tree support for both the
interrupt and GPIO controllers of AT91 SoC. It has been discussed a lot
and I think that I have addressed all comments and advices.

This irqdomain work takes advantage of Grant's patch series that is present
in:
git://git.secretlab.ca/git/linux-2.6 irqdomain/next
And it will not compile without it. So, the inclusion of such work is needed
before we can apply this series on mainline.

On the other hand, I have not included Grant's branch in mine on purpose: All
this simply goes on top of current AT91 material that is already in arm-soc
(merge of all at91/* branches). You can find it in the AT91 git tree with
at91-3.4-base2 branch name). I have made merge tests and all seems to integrate
without conflicts.
