Subject: [PATCH v2 02/20] power: supply: bq25890: Fix ADC continuous conversion setting when charging

From: Yauhen Kharuzhy <jekhor@...il.com>

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.).
