V7: * Pass only necessary data to the drivers registered by imx-otg
      (memory, irq, pointer to imx-otg device). This should fix issue
pointed
      out by Lothar Wassmann.
    * Have single IRQ handler in imx-otg, which then calls host/gadget
IRQ
      handlers only if they're registered via imx_otg_set_irq_handler()
call,
      depending on the current state of the OTG.

 
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)?
