I see the conversions have been made the brute-force way instead of keeping backwards compatibility and cleaning up drivers before removing no longer needed board code. That should be fine, as long as you don't introduce too crazy dependencies (and conflicts) in the code you're talking about adding on top. -Olof

The platform devices which we converted over were either already converted (mmci, amba-pl011), not used (crypt, hash, musb) or broken (mop500-asoc). So it really should be no big deal.
Hi ARM SoC folks, here is a patch set that Lee has been chiseling out recently. I've accumulated it in my ux500 tree and piled ACKs on the first 36 patches of the patch set. Basically that includes ACKs from subsystem maintainers Vinod Koul and Herbert Xu for affected parts. We need to get this into Linux-next to proceed with further migration on top of it. All have been circulated on the lists for a while. Please pull this into an apropriate ARM SoC branch for v3.11! If we can get ACKs for the rest of the patches in Lee's set these will arrive on top of this base as soon as they are ready.
