Indeed, I've been using the patchset "Add tested id switch and vbus
connect detect support for Chipidea" from Peter for quite some time on
top of 3.9 and it works like a charm for the gadget mode on an MX28
platform.

BTW, Peter, I've seen that these patches are still not merged in 3.10,
is there a reason for that? do you plan on sending a version rebased on
top of 3.10 some time in the future? I tried to do the rebasing myself,
but the chipidea driver seems to have changed quite heavily, which makes
the process quite difficult when you don't know what you're doing :)

Thanks!
Maxime
