+Description:
+               This entry configures the overvoltage protection feature of bq24257-
+               type charger devices. This feature protects the device and other
+               components against damage from overvoltage on the input supply. See
+               device datasheet for details.

+Description:
+               This entry configures the input dynamic power path management voltage of
+               bq24257-type charger devices. Once the supply drops to the configured
+               voltage, the input current limit is reduced down to prevent the further
+               drop of the supply. When the IC enters this mode, the charge current is
+               lower than the set value. See device datasheet for details.

+Description:
+               This entry allows enabling the high-impedance mode of bq24257-type
+               charger devices. If enabled, it places the charger IC into low power
+               standby mode with the switch mode controller disabled. When disabled,
+               the charger operates normally. See device datasheet for details.

+Description:
+               This entry allows enabling the sysoff mode of bq24257-type charger
+               devices. If enabled and the input is removed, the internal battery FET
+               is turned off in order to reduce the leakage from the BAT pin to less
+               than 1uA. Note that on some devices/systems this disconnects the battery
+               from the system. See device datasheet for details.
