+Low-Battery Monitor:
+==================
+max77620 is able to monitor the main battery voltage and shutdown/reset the
+chip connected accordingly.
+
+Optional properties:
+	- maxim,low-battery-dac-enable: Enable low battery monitoring.
+			Low battery monitoring will be disabled if missing
+			this property.
+	- maxim,low-battery-mode: Shutdown or reset the chip.
+			The value of this property is "shutdown" which means
+			a global shutdown will be triggered. Any other values
+			or missing this property causes a chip reset.
+
 Example:
 --------
 #include <dt-bindings/mfd/max77620.h>
