i2cdump was easily built, so here is the output:

I checked the value at 0x84 (channel 0, and using single-ended and 
external reference). I got 222 when reading from corresponding sysfs, 
and 0x131 * lsb_resolution (806) / 1000 is 222 in decimal. So it seems 
as data above is correct.

Is the data what you expected?
