0001 * Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards
0002
0003 Required properties:
0004 - compatible            : "snps,arc-uart"
0005 - reg                   : offset and length of the register set for the device.
0006 - interrupts            : device interrupt
0007 - clock-frequency       : the input clock frequency for the UART
0008 - current-speed         : baud rate for UART
0009
0010 e.g.
0011
0012 arcuart0: serial@c0fc1000 {
0013         compatible = "snps,arc-uart";
0014         reg = <0xc0fc1000 0x100>;
0015         interrupts = <5>;
0016         clock-frequency = <80000000>;
0017         current-speed = <115200>;
0018 };
0019
0020 Note: Each port should have an alias correctly numbered in "aliases" node.
0021
0022 e.g.
0023 aliases {
0024         serial0 = &arcuart0;
0025 };
