1	* Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards
2	
3	Required properties:
4	- compatible		: "snps,arc-uart"
5	- reg			: offset and length of the register set for the device.
6	- interrupts		: device interrupt
7	- clock-frequency	: the input clock frequency for the UART
8	- current-speed		: baud rate for UART
9	
10	e.g.
11	
12	arcuart0: serial@c0fc1000 {
13		compatible = "snps,arc-uart";
14		reg = <0xc0fc1000 0x100>;
15		interrupts = <5>;
16		clock-frequency = <80000000>;
17		current-speed = <115200>;
18		status = "okay";
19	};
20	
21	Note: Each port should have an alias correctly numbered in "aliases" node.
22	
23	e.g.
24	aliases {
25		serial0 = &arcuart0;
26	};
