+=== AB8500 Battery Temperature Monitor Driver ===
+
+The properties below describes the node for btemp driver.
+
+Required Properties:
+- compatible = Shall be: "stericsson,ab8500-btemp"
+- battery = Shall be battery specific information
+
+        Example:
+        ab8500_btemp {
+                compatible = "stericsson,ab8500-btemp";
+                battery    = <&ab8500_battery>;
+        };
+
+For information on battery specific node, Ref:
