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 | - baud : 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 | baud = <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 | }; |
