We still have to address some of Sarah's comments to the original patchset and that's why it didn't go on 3.3 merge window. If you really, really need host mode, you can go over the mailing list archives, fetch the original patch from Sebastian, fix Sarah's comments, test on your platform and send a v2 of the patch. When doing so, please mention which platform and which RTL revision you're using so we can keep track of which RTL versions have been tested on which SoCs. -- balbi
