+Actions Semi Owl UART
+
+Required properties:
+- compatible :  "actions,s500-uart", "actions,owl-uart" for S500
+                "actions,s900-uart", "actions,owl-uart" for S900
+- reg        :  Offset and length of the register set for the device.
+- interrupts :  Should contain UART interrupt.
+
+
+Example:
+
+		uart3: serial@b0126000 {
+			compatible = "actions,s500-uart", "actions,owl-uart";
+			reg = <0xb0126000 0x1000>;
+			interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+		};
