* 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>;
status = "okay";
};
Note: Each port should have an alias correctly numbered in "aliases" node.
e.g.
aliases {
serial0 = &arcuart0;
};
