Subject: power: bq25890: Enable continuous conversion for ADC at charging
From: Yauhen Kharuzhy <jekhor@xxxxxxxxx>
commit 80211be1b9dec04cc2805d3d81e2091ecac289a1 upstream.
Instead of one shot run of ADC at beginning of charging, run continuous
conversion to ensure that all charging-related values are monitored
properly (input voltage, input current, themperature etc.).
