* 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. * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
