1	* Freescale MXS Application UART (AUART)
2	
3	Required properties:
4	- compatible : Should be "fsl,<soc>-auart". The supported SoCs include
5	  imx23 and imx28.
6	- reg : Address and length of the register set for the device
7	- interrupts : Should contain the auart interrupt numbers
8	- dmas: DMA specifier, consisting of a phandle to DMA controller node
9	  and AUART DMA channel ID.
10	  Refer to dma.txt and fsl-mxs-dma.txt for details.
11	- dma-names: "rx" for RX channel, "tx" for TX channel.
12	
13	Optional properties:
14	- fsl,uart-has-rtscts : Indicate the UART has RTS and CTS lines,
15		it also means you enable the DMA support for this UART.
16	
17	Example:
18	auart0: serial@8006a000 {
19		compatible = "fsl,imx28-auart", "fsl,imx23-auart";
20		reg = <0x8006a000 0x2000>;
21		interrupts = <112>;
22		dmas = <&dma_apbx 8>, <&dma_apbx 9>;
23		dma-names = "rx", "tx";
24	};
25	
26	Note: Each auart port should have an alias correctly numbered in "aliases"
27	node.
28	
29	Example:
30	
31	aliases {
32		serial0 = &auart0;
33		serial1 = &auart1;
34		serial2 = &auart2;
35		serial3 = &auart3;
36		serial4 = &auart4;
37	};
