* 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,irda-mode : Indicate the uart supports irda mode
- fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
                  in DCE mode by default.

Please check Documentation/devicetree/bindings/serial/serial.txt
for the complete list of generic properties.

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>;
	uart-has-rtscts;
	fsl,dte-mode;
};
