+* Freescale i.MX Universal Asynchronous Receiver/Transmitter (UART)
+
+Required properties:
+- compatible : Should be "fsl,<soc>-uart"
+- reg : Address and length of the register set for the device
+- interrupts : Should contain uart interrupt
+
+Optional properties:
+- fsl,uart-has-rtscts : Indicate the uart has rts and cts
+- fsl,irda-mode : Indicate the uart supports irda mode
+- fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
+                  is DCE mode by default.
+
+Note: Each uart controller should have an alias correctly numbered
+in "aliases" node.
+
+Example:
+
+aliases {
+       serial0 = &uart1;
+};
+
+uart1: serial@73fbc000 {
+       compatible = "fsl,imx51-uart", "fsl,imx21-uart";
+       reg = <0x73fbc000 0x4000>;
+       interrupts = <31>;
+       fsl,uart-has-rtscts;
+       fsl,dte-mode;
+};
