+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.

+Contact: Andreas Dannenberg <dannenberg@ti.com>
+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.
