- Disabled increasing VDDMAX in qpnp-charger - Fixed non-charging issue after flashlight has been turned off while charging - Enabled battery swelling protection (CONFIG_BATTERY_SWELLING) in sec-battery to s3ve3g devices (proper configs are defined in battery header already) - Enabled prevent SOC jump. The battery driver will slowly add a SOC until it's 100 when the average current is below 170 and min SOC is 93 - Reduced minimum expected full condition SOC from 95 to 93 - Removed 'ext-ovp-present' bool from device tree as only qpnp-sec-charger calls it - Reworked default high battery temperature threshold/recovery (60°C/47°C to 58°C/53°C) also while in LPM - Switched from Qualcomm's flash-boot-supply to Samsung's flash regulator disabler/enabler - Switched from time measure check type (2400 mins) to current check type (<170mA) while charging to report full charged condition Change-Id: Id74e3d9497d381a389ae56096c61dfa7200a83cf
