Ivan,

Do you have patches for the code (presumably pmic code) where the vbus and id
lines are signaled?  Presumably you've added some extcon_set_cable_state() calls
somewhere in your source tree, for this to work.  I'm wondering if you
can share your
work in progress, or let me know when you plan to push that upstream?

I'm interested in testing the msm usb code (specifically host mode support)
on my dragonboard here.

Thanks,
 -- Tim
