if i get it right the real intention of this patch series is to make the
mxs-lradc provide resistance values instead of voltages. So how about
dropping the whole regulator stuff and provide the values as
IIO_RESISTANCE via iio interface?
Btw this feature should be only added to dts files where is actually used.

Stefan
