The smb137b chip from SUMMIT is a Switch Mode charger chip capable of charging through USB source. It can also provide VBUS when the system is a host. The driver exposes the charger properties via the power_supply class. It also interacts with the usb driver for insertion/removal notifications and charge current information. The driver also turns off charging and switches to providing VBUS when told to do so by USB driver.
