   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 };
