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

[Nicolas Ferre]

Hi,

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.


The following changes since commit 11a25ea7e4f870a37093258f577e11cec703e37e:

  Merge remote-tracking branch 'armsoc/at91/9x5' into at91-3.4-base2 (2012-02-11 14:33:03 +0100)
