3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible		: "snps,arc-uart"
5*4882a593Smuzhiyun- reg			: offset and length of the register set for the device.
6*4882a593Smuzhiyun- interrupts		: device interrupt
7*4882a593Smuzhiyun- clock-frequency	: the input clock frequency for the UART
8*4882a593Smuzhiyun- current-speed		: baud rate for UART
