It belongs in Doc.../power/supply/battery.txt if it's a characteristic of the battery. Note, this page asserts that constant-current charging applies to NiMH batteries: http://power-topics.blogspot.com/2016/05/constant-voltage-constant-current.html Related properties to be added to battery.txt near-future in a patchset for the BQ24190 charger are as follows. These are not currently in enum power_supply_property, so the actual names are still to be decided. precharge-current-microamp: maximum charge current during precharge phase (typically 20% of battery capacity) termination-current-microamp (or endcharge-current): a charge cycle terminates when the battery voltage is above recharge threshold, and the current is below this setting (typically 10% of battery capacity) ~.~ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
