101 driver first appeared in
113 driver was written by
118 .An Alexander Yurchenko Aq grange@openbsd.org .
119 The driver was largely rewritten for
122 .An Mark Kettenis Aq kettenis@openbsd.org .
123 The driver was then ported to
126 .An Constantine A. Murenin Aq cnst@FreeBSD.org
127 as a part of a Google Summer of Code 2007 project.
129 Some vendors connect these chips to non-standard thermal diodes and
131 This will result in bogus sensor values.
133 Interrupt support is unimplemented.
135 There are currently no known pnpbios IDs assigned to LM chips.
137 This driver attaches to the Winbond W83791SD chip even though that
138 chip does not have any sensors.
