The notifier call that is called in the usb driver is not only for the battery driver but other usb instances, hence usb cannot stop calling the notifier call and do a check to call only if it is a standard host.

State is not as accurate as reading it directly from the usb controller. This should not matter as battery- manager driver should care more about mA than the state anyway.

2011-09-19power: ab5500-fg: Proper registering of power supplyArun Murthy
During boot if the battery voltage exceed the max voltage, then an interrupt is triggered to the GPADC for auto control. This in turn will call the fg registered callback handler. But this happens before the power supply class of fg is registered. Thereby calling power_supply_changed() will lead to BUG since it used the wake lock which has not yet been initializes. Hence register power supply class for fg first followed by initializing the hardware registers, which includes registering for a gpadc auto convert for battery voltage.

A generic charging algorithm for all abx500 varants. It is a high level algorithm and hence doesn't include any low level or hardware interaction. Each of the abx500 charging drivers will implement low level hardware interaction function and provide inputs to this generic charging algorithm to monitor and implement the charging functionality.

Remove usb_state_changed() exported function. Replace it with otg notifier call. This makes static_di redundant so it is removed. Moreover, there is no need to protect usb_state.usb_changed with usb_lock. So usb_lock is removed as well. Usb state is fabricated based on the reported mA. State is not as accurate as reading it directly from the usb controller. This should not matter as battery- manager driver should care more about mA than the state anyway.
