| |
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)
