|  | * Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards | 
|  |  | 
|  | Required properties: | 
|  | - compatible		: "snps,arc-uart" | 
|  | - reg			: offset and length of the register set for the device. | 
|  | - interrupts		: device interrupt | 
|  | - clock-frequency	: the input clock frequency for the UART | 
|  | - current-speed		: baud rate for UART | 
|  |  | 
|  | e.g. | 
|  |  | 
|  | arcuart0: serial@c0fc1000 { | 
|  | compatible = "snps,arc-uart"; | 
|  | reg = <0xc0fc1000 0x100>; | 
|  | interrupts = <5>; | 
|  | clock-frequency = <80000000>; | 
|  | current-speed = <115200>; | 
|  | }; | 
|  |  | 
|  | Note: Each port should have an alias correctly numbered in "aliases" node. | 
|  |  | 
|  | e.g. | 
|  | aliases { | 
|  | serial0 = &arcuart0; | 
|  | }; |
