Now I see how it works. I2C devices should be created before driver 
loading. There was my mistake, and driver does not call probe() 
function. Maybe would be better to create I2C devices by driver itself, 
not by the board specific config code? Now sensor driver is useless 
itself, without board specific configuration... Would be correct to do so?

Thanks,
Darius.
