- Stop charging when thermal limits are violated. - Don't start charging if battery percent is above 95% (but continue to charge if we're already charging). - Don't allow battery voltage to get too close (10mA) to BD9995X VBAT setting. If battery voltage exceeds VBAT then back boosting may occur. BUG=chrome-os-partner:56255 BRANCH=gru TEST=Manual on kevin, insert charger with battery at 97%, verify battery doesn't charge and reported current is 0. Discharge down to 95% and insert charger, verify battery charges. Charge to 100%, verify battery stops requesting current.
