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}; 26
