    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 };
   19 
   20 Note: Each port should have an alias correctly numbered in "aliases" node.
   21 
   22 e.g.
   23 aliases {
   24         serial0 = &arcuart0;
   25 };
