+ * lm63.c - driver for the National Semiconductor LM63 temperature sensor
+ *          with integrated fan control
+ * Copyright (C) 2004  Jean Delvare <khali@linux-fr.org>
+ * Based on the lm90 driver.
+ *
+ * The LM63 is a sensor chip made by National Semiconductor. It measures
+ * two temperatures (its own and one external one) and the speed of one
+ * fan, those speed it can additionally control. Complete datasheet can be
+ * obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM63.html
+ *
+ * The LM63 is basically an LM86 with fan speed monitoring and control
+ * capabilities added. It misses some of the LM86 features though:
+ *  - No low limit for local temperature.
+ *  - No critical limit for local temperature.
+ *  - Critical limit for remote temperature can be changed only once. We
+ *    will consider that the critical limit is read-only.
+ *
+ * The datasheet isn't very clear about what the tachometer reading is.
+ * I had a explanation from National Semiconductor though. The two lower
+ * bits of the read value have to be masked out. The value is still 16 bit
+ * in width.
