Hi,

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.
