Nanopi Neo I2C

[lyd mc]

Hi List,
Can you help me make I2C work in this board?
I can detect the controller but cannot access it through iic ioctl. 

root at nanopi-neo:~/prog/I2C # dmesg |grep iic
iichb0: <Allwinner Integrated I2C Bus Controller> mem 0x1c2ac00-0x1c2afff irq 34 on simplebus0
iicbus0: <OFW I2C bus> on iichb0
iichb1: <Allwinner Integrated I2C Bus Controller> mem 0x1c2b000-0x1c2b3ff irq 35 on simplebus0
iicbus1: <OFW I2C bus> on iichb1
iichb2: <Allwinner Integrated I2C Bus Controller> mem 0x1c2b400-0x1c2b7ff irq 36 on simplebus0
iicbus2: <OFW I2C bus> on iichb2
iic0: <I2C generic I/O> on iicbus0
iic1: <I2C generic I/O> on iicbus1
iic2: <I2C generic I/O> on iicbus2

kdump output:

  1290 mcp      NAMI  "/dev/iic0"
  1290 mcp      RET   openat 3
  1290 mcp      CALL  ioctl(0x3,I2CRDWR,0xbfbfecd4)
  1290 mcp      RET   ioctl -1 errno 2 No such file or directory

This seems to work on my RPI.
