GL-MV1000 Brume - Activating I2C

I am trying to use I2C on the GL-MV1000 Brume. dmesg shows i2c /dev entries driver and i2c_gpio module is loaded, but no devices /dev/i2c*:

root@mv1000-2:~# dmesg | grep i2c
[   10.678647] i2c /dev entries driver
root@mv1000-2:~# lsmod | grep i2c
i2c_algo_bit           16384  1 i2c_gpio
i2c_core               32768  4 i2c_gpio,i2c_smbus,i2c_algo_bit,i2c_dev
i2c_dev                20480  0 
i2c_gpio               16384  0 
i2c_smbus              16384  0 
root@mv1000-2:~# ls -l /dev/i2c*
ls: /dev/i2c*: No such file or directory

What else is required to activate i2c on GL-MV1000?

But have you connected anything to I2C interface.

I even don’t know there is one or not.
