Ok since it doesn't look like this will resolve soon, what about
adding some DEVICE_ATTR for the time being and requiring userspace to
write charge current here to start actual charging?

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@xxxxxxxxxxxxx> for suggesting that.
