+Backup Battery:
+==============
+This sub-node configure charging backup battery of the device. Device has
+support of charging the backup battery. The subnode name is "backup-battery".
+The property for backup-battery child nodes as:
+Presence of this child node will enable the backup battery charging.
+
+Optional properties:
+ -maxim,backup-battery-charging-current: Charging current setting.
+ The device supports 50/100/200/400/600/800uA.
+ If this property is unavailable then it will
+ charge with 50uA.
+ -maxim,backup-battery-charging-voltage: Charging Voltage Limit Setting.
+ Device supports 2500000/3000000/3300000/350000uV.
+ Default will be set to 2500mV. The voltage will be roundoff
+ to nearest lower side if other than above is configured.
+ -maxim,backup-battery-output-resister: Output resistor on Ohm.
+ Device supports 100/1000/3000/6000 Ohms.
+ Default will be set to 1000 Ohm.
