    We can get the charging current from configuration.

    When gadget driver call usb_gadget_vbus_draw() we can use that to pass
    the information somewhere else.

    But what I'm doing now is implementing an atomic_notifier which will
    call whatever function another driver want whenever we have twl4030-usb
    irqs.

    We can use that to kick the charger detection itself (on twl4030-usb)
    and you can register your notifier_block callback to enable charging as
    you wish.

    Then we will have the charger detection done on the right place
    (twl4030-usb) and the charging start done on the right place
    (twl4030-bci or bq24xxx).

    Thanks to Anton Vorontsov <avorontsov@ru.mvista.com> for suggesting
    that.
