+~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "maxim,max17040"
+
+Optional threshold properties :
+ If skipped the power up default value will be used
+ - maxim,alert-soc-level : The alert threshold that sets the state of
+ charge level where an interrupt is generated.
+ max17040 can be configured from 1 up to 32.
+
+Remembering that for the interrupt to be handled it must also be described the
+information of the interruption in the node.
+
+Example:
+
+ battery-charger@36 {
+ compatible = "maxim,max17040";
+ reg = <0x36>;
+ maxim,alert-soc-level = <10>;
+ interrupt-parent = <&gpio>;
+ interrupts = <18 IRQ_TYPE_EDGE_FALLING>;
+ };
