+ * This driver also supports the LM89 and LM99, two other sensor chips
+ * made by National Semiconductor. Both have an increased remote
+ * temperature measurement accuracy (1 degree), and the LM99
+ * additionally shifts remote temperatures (measured and limits) by 16
+ * degrees, which allows for higher temperatures measurement. The
+ * driver doesn't handle it since it can be done easily in user-space.
+ * Complete datasheets can be obtained from National's website at:

+ * Note that there is no way to differenciate between both chips.
