2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible      : should be "netlogic,xlp980-i2c"
5*4882a593Smuzhiyun- reg             : bus address start and address range size of device
6*4882a593Smuzhiyun- interrupts      : interrupt number
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunOptional properties:
9*4882a593Smuzhiyun- clock-frequency : frequency of bus clock in Hz
10*4882a593Smuzhiyun                    Defaults to 100 KHz when the property is not specified
