1	* Freescale low power universal asynchronous receiver/transmitter (lpuart)
2	
3	Required properties:
4	- compatible : Should be "fsl,<soc>-lpuart"
5	- reg : Address and length of the register set for the device
6	- interrupts : Should contain uart interrupt
7	- clocks : phandle + clock specifier pairs, one for each entry in clock-names
8	- clock-names : should contain: "ipg" - the uart clock
9	
10	Optional properties:
11	- dmas: A list of two dma specifiers, one for each entry in dma-names.
12	- dma-names: should contain "tx" and "rx".
13	
14	Note: Optional properties for DMA support. Write them both or both not.
15	
16	Example:
17	
18	uart0: serial@40027000 {
19			compatible = "fsl,vf610-lpuart";
20			reg = <0x40027000 0x1000>;
21			interrupts = <0 61 0x00>;
22			clocks = <&clks VF610_CLK_UART0>;
23			clock-names = "ipg";
24			dmas = <&edma0 0 2>,
25				<&edma0 0 3>;
26			dma-names = "rx","tx";
27		};
