Driver: ISL9237: Enable trickle charging
Enabled the trickle charging mode by setting the MinSystemVoltage
register[0x3EH] to board specific battery voltage minimum value.
When the battery voltage drops below the battery voltage minimum
value, trickle charging enabled.
BUG=none
TEST=Manually tested on Kunimitsu FAB4 prototype.
Drained the battery below voltage minimum value. Using the
i2cxfer command observed Trickle charging mode is active in
the information register[0x3AH].
