1* Freescale i.MX Universal Asynchronous Receiver/Transmitter (UART)
2
3Required properties:
4- compatible : Should be "fsl,<soc>-uart"
5- reg : Address and length of the register set for the device
6- interrupts : Should contain uart interrupt
7
8Optional properties:
9- fsl,dte-mode : Indicate the uart works in DTE mode. The uart works
10 in DCE mode by default.
11- rs485-rts-delay, rs485-rts-active-low, rs485-rx-during-tx,
12 linux,rs485-enabled-at-boot-time: see rs485.txt
13
14Please check Documentation/devicetree/bindings/serial/serial.txt
15for the complete list of generic properties.
16
17Note: Each uart controller should have an alias correctly numbered
18in "aliases" node.

20Example:
21
22aliases {
23 serial0 = &uart1;
24};
25
26uart1: serial@73fbc000 {
27 compatible = "fsl,imx51-uart", "fsl,imx21-uart";
28 reg = <0x73fbc000 0x4000>;
29 interrupts = <31>;
30 uart-has-rtscts;
31 fsl,dte-mode;
32};
