The HSCDTD008A has 15 bits of actual ADC valie, and the AMI305 and AMI306 has 12 bits. Correct this by providing an extra parameter to the channel macro and define a separate set of channels for each variant of the chip. The resolution is the actual resolution of the internal ADC of the chip. The values are stored in a S16 in 2's complement so all 16 bits are used for storing (no shifting needed). The AMI305, AMI306 and HSCDTD008A valid bits are picked from respective datasheet. My best educated guess is that AK8974 is also 12 bits. The AK8973 is an 8 bit and earlier version, and the sibling drivers AMI305 and AMI306 are 12 bits, so it makes sense to assume that the AK8974 is also 12 bits.
