 While the DS1621 has three additional bits of accuracy
 (12 vs. 9 for the LM75), the additional bits are not supported.
 
+The driver also supports the DS1625. It does not distinguish the 1625 from
+the 1621. The chip prefix in /proc is always ds1621.
+The difference in the chips is that the 1621 supports additional registers
+for greater accuracy. The driver does not use these registers.
+The DS1625 has been discontinued by Dallas Semi, they recommend the
+DS1621 for new designs.
