I2C/IIC working on RPI4 8GB?

[Hrant Dadivanyan]

Yes, this helps me too:
iichb0: <BCM2708/2835 BSC controller> mem 0x7e804000-0x7e804fff irq 26 
on simplebus0
iicbus0: <OFW I2C bus> on iichb0
iic0: <I2C generic I/O> on iicbus0
ds32310: <Maxim DS3231 RTC> at addr 0xd0 on iicbus0
ds32310: registered as a time-of-day clock, resolution 1.000000s

Thank you!
