 The chips supported by this driver are very similar. The Maxim MAX1617
 is the oldest; it has the problem that it is not very well detectable.
 The MAX1617A solves that.  The ADM1021 is a straight clone of the MAX1617A.
+Ditto for the THMC10.
 From here on, we will refer to all these chips as ADM1021-clones.

 ADM1021-clones implement two temperature sensors. One of them is internal,
