=== 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>;

	};
