This patch allows machines to use an OTG transceiver driver instead of supplying a custom is_usb_online callback to check USB power. Also, in the case that the OTG transceiver handles charger control when connected to USB, a regulator named "ac_draw" can be supplied instead of the custom set_charge callback to control the charger when connected to AC. The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in otg_is_usb_online is probably too simple, I'm just using this with a peripheral only device and gpio_vbus + bq24022. I'm not sure which other OTG states can supply power. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
