-max17040_battery
-~~~~~~~~~~~~~~~~
-
-Required properties :
- - compatible : "maxim,max17040", "maxim,max17041", "maxim,max17043",
-		"maxim,max17044", "maxim,max17048", "maxim,max17049",
-		"maxim,max17058", "maxim,max17059" or "maxim,max77836-battery"
- - reg: i2c slave address
-
-Optional properties :
-- maxim,alert-low-soc-level :	The alert threshold that sets the state of
-				charge level (%) where an interrupt is
-				generated. Can be configured from 1 up to 32
-				(%). If skipped the power up default value of
-				4 (%) will be used.
-- maxim,double-soc : 		Certain devices return double the capacity.
-				Specify this boolean property to divide the
-				reported value in 2 and thus normalize it.
-				SOC == State of Charge == Capacity.
-- maxim,rcomp :			A value to compensate readings for various
-				battery chemistries and operating temperatures.
-				max17040,41 have 2 byte rcomp, default to
-				0x97 0x00. All other devices have one byte
-				rcomp, default to 0x97.
-- interrupts : 			Interrupt line see Documentation/devicetree/
-				bindings/interrupt-controller/interrupts.txt
-- wakeup-source :		This device has wakeup capabilities. Use this
-				property to use alert low SOC level interrupt
-				as wake up source.
-
-Optional properties support interrupt functionality for alert low state of
-charge level, present in some ICs in the same family, and should be used with
-compatible "maxim,max77836-battery".
-
-Example:
-
-	battery-fuel-gauge@36 {
-		compatible = "maxim,max77836-battery";
-		reg = <0x36>;
-		maxim,alert-low-soc-level = <10>;
-		interrupt-parent = <&gpio7>;
-		interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
-		wakeup-source;
-	};
-
-	battery-fuel-gauge@36 {
-		compatible = "maxim,max17048";
-		reg = <0x36>;
-		maxim,rcomp = /bits/ 8 <0x56>;
-		maxim,alert-low-soc-level = <10>;
-		maxim,double-soc;
-	};
