+* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
+
+Required properties:
+- compatible: Should be "cirrus,clps711x-uart".
+- reg: Address and length of the register set for the device.
+- interrupts: Should contain UART TX and RX interrupt.
+- clocks: Should contain UART core clock number.
+- syscon: Phandle to SYSCON node, which contain UART control bits.
+
+Optional properties:
+- uart-use-ms: Indicate the UART has modem signal (DCD, DSR, CTS).
+- uart-use-irda: Indicate the UART use IRDA mode.
+
+Note: Each UART port should have an alias correctly numbered
+in "aliases" node.
+
+Example:
+	aliases {
+		serial0 = &uart1;
+	};
+
+	uart1: uart at 80000480 {
+		compatible = "cirrus,clps711x-uart";
+		reg = <0x80000480 0x80>;
+		interrupts = <12 13>;
+		clocks = <&clks 11>;
+		syscon = <&syscon1>;
+		uart-use-ms;
+	};
