GIC DT binding support

Arnd,

I'm not sure if you want a rebased branch to fix merge conflicts or not. If that's okay, please pull. I've also fixed the msm compile failure.

The dependencies are v3.1-rc9 and rmk's devel-stable.

The following changes since commit 3a8254364277fabe01bc0e12b9691722939f5ef3:

Arnd,

Here's an updated pull request to fix missing export.h include. Now it's also dependent on module.h clean-up branch:

I've pulled it and am now trying to clean up the mess resulting from having the previous version in a number of branches already.

Can you check that the highbank/soc branch is ok this time?

Arnd

Rob, I think there is no chance that this is working out.

I've just spent a few hours trying to resolve all the dependencies from this, but I don't think it will work out, unless Linus pulls that tree very soon, which I think is very unlikely.

Have you made sure that Paul even considers this branch stable?

Normally this kind of change gets pushed *last* in the merge window, to make it possible to fix up all the stuff that breaks. This means I cannot wait for the branch to get merged upstream before send a pull request for my next/dt and next/soc branches.

Do you even depend on that branch? It seems to me that you merely have a conflict, not a dependency, so why do you even try fixing it up?

Arnd

Arnd,

No.

Sorry about this. I thought I needed to fix the linux-next build breakage. I only depend on it when export.h gets introduced, so I can drop that out. All the other dependencies are in Linus' master now. I pushed out a branch without Paul's branch:

I get to Connect around 2PM tomorrow, we can discuss further then if necessary.
