* 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; };
