* Synopsys ARC UART : Non standard UART used in some of the ARC FPGA boards
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "snps,arc-uart"
|
||
|
|
- reg : offset and length of the register set for the device.
|
||
|
|
- interrupts : device interrupt
|
||
|
|
- clock-frequency : the input clock frequency for the UART
|
||
|
|
- current-speed : baud rate for UART
|
||
|
|
|
||
|
|
e.g.
|
||
|
|
|
||
|
|
arcuart0: serial@c0fc1000 {
|
||
|
|
compatible = "snps,arc-uart";
|
||
|
|
reg = <0xc0fc1000 0x100>;
|
||
|
|
interrupts = <5>;
|
||
|
|
clock-frequency = <80000000>;
|
||
|
|
current-speed = <115200>;
|
||
|
|
};
|
||
|
|
|
||
|
|
Note: Each port should have an alias correctly numbered in "aliases" node.
|
||
|
|
|
||
|
|
e.g.
|
||
|
|
aliases {
|
||
|
|
serial0 = &arcuart0;
|
||
|
|
};
