+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>;
+};
