+SBS sbs-charger
+~~~~~~~~~~
+
+Required properties:
+ - compatible: should contain one of the following:
+	- "lltc,ltc4100"
+	- "sbs,sbs-charger"
+
+Optional properties:
+- interrupt-parent: Should be the phandle for the interrupt controller. Use in
+    conjunction with "interrupts".
+- interrupts: Interrupt mapping for GPIO IRQ. Use in conjunction with
+    "interrupt-parent". If an interrupt is not provided the driver will switch
+    automatically to polling.
+
+Example:
+
+	ltc4100@9 {
+		compatible = "sbs,sbs-charger";
+		reg = <0x9>;
+		interrupt-parent = <&gpio6>;
+		interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
+	};
