Subject: [PATCH v2 2/4] 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.

+max17040_battery
+~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "maxim,max17040" or "maxim,max77836-battery"
+
+Optional properties :
+- maxim,alert-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.
+- interrupt-parent : 		The GPIO bank from the interrupt line.
+- interrupts : 			Interrupt line see Documentation/devicetree/
+				bindings/interrupt-controller/interrupts.txt
+
+Example:
+
+	battery-charger@36 {
+		compatible = "maxim,max17040";
+		reg = <0x36>;
+		maxim,alert-soc-level = <10>;
+		interrupt-parent = <&gpio7>;
+		interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
+	};
