The bma180 is not compatible with the bma150 at all, it has 14 bits resolution instead of 10, and it has quite different control registers. Treating the bma180 as a bma150 wrt its data registers will just result in throwing away the lowest 4 bits, which is not too bad. But the ctrl registers are a different story. It may be that things happen to just work (I don't have a bma180 to test with) but that certainly does not make this right. Removing the bma180 id also removes overlap wrt the ids in the iio bma180 driver which does treat the bma180 properly. Cc: Dr. H.
