Subject: [PATCH 3/4] dt-bindings: power: supply: Max17040: Add low level SOC alert threshold

For configure low level state of charge threshold alert signaled from
max17040 we add "maxim,alert-soc-level" property.

+~~~~~~~~~~~~~~~~
+
+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>;
+	};
