+max17042_battery
+~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "maxim,max17042"
+
+Optional properties :
+ - maxim,rsns-microohm : Resistance of rsns resistor in micro Ohms
+                         (datasheet-recommended value is 10000).
+   Defining this property enables current-sense functionality.
+
+Example:
+
+        battery-charger@36 {
+                compatible = "maxim,max17042";
+                reg = <0x36>;
+                maxim,rsns-microohm = <10000>;
+        };
