+ARM MPS2 UART
+
+Required properties:
+- compatible	: Should be "arm,mps2-uart"
+- reg		: Address and length of the register set
+- interrupts	: Reference to the UART RX, TX and overrun interrupts
+
+Required clocking property:
+- clocks	  : The input clock of the UART
+
+
+Examples:
+
+uart0: serial@40004000 {
+	compatible = "arm,mps2-uart";
+	reg = <0x40004000 0x1000>;
+	interrupts = <0 1 12>;
+	clocks = <&sysclk>;
+};
