[GIT PULL v2] at91: irqdomain and device tree for 3.4

[Nicolas Ferre]

Hi Arnd and Olof,

This pull request supersedes the previous:
"[GIT PULL] at91: irqdomain and device tree for AIC and GPIO"

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.

To the AIC, GPIO device tree work, it also adds the the conversion of the 
PIT and TC timers, the PIO3 support and some basic LED and gpio-keys entries.

The irqdomain work takes advantage of Grant's patch series that is present
in:
git://git.secretlab.ca/git/linux-2.6 irqdomain/next
This branch is merged into this tree, on top of at91/base2+cleanup (aka cleanup2)
and before the application of new AT91 material.


The following changes since commit 89d4a1753b6632327f18d6c8e0842b366b736621:

  Merge branch 'irqdomain/next' of git://git.secretlab.ca/git/linux-2.6 (2012-03-01 13:26:51 +0100)
