1* Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards
2
3Required 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
10e.g.
11
12arcuart0: serial@c0fc1000 {
13 compatible = "snps,arc-uart";
14 reg = <0xc0fc1000 0x100>;
15 interrupts = <5>;
16 clock-frequency = <80000000>;
17 current-speed = <115200>;
18};
19
20Note: Each port should have an alias correctly numbered in "aliases" node.
21
22e.g.
23aliases {
24 serial0 = &arcuart0;
25};
