Hi Marek,

If the host and device interrupt handler are called by otg interrupt handler,
then, the interrupt handlers are registered by host/device will be called twice
as they are also registered by host/device themselves.

Besides, what kinds of function do you want to add at this patchset?
device-only?host-only? basic otg (id switch)? power management (As I have seen you add
wakeup interrupt handler)?
