[PATCH 09/15] power: supply: bq24190_charger: Add voltage_max_design prop to battery

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When combined with an external fuel-gauge, upower needs voltage_max_design
as it internally does all its calculations in Watts and converts the
charge_foo properties from A to Watts by using voltage_max_design.
