+max17040_battery
+~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "maxim,max17040" or "maxim,max77836-battery"
+
+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.
+- 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.
+
+Example:
+
+ battery-fuel-gauge@36 {
+ compatible = "maxim,max17040";
+ reg = <0x36>;
+ maxim,alert-low-soc-level = <10>;
+ interrupt-parent = <&gpio7>;
+ interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
+ wakeup-source;
+ };
