14	Description
15	-----------
17	The W83L785TS-S is a digital temperature sensor. It senses the
18	temperature of a single external diode. The high limit is
19	theoretically defined as 85 or 100 degrees C through a combination
20	of external resistors, so the user cannot change it. Values seen so
21	far suggest that the two possible limits are actually 95 and 110
22	degrees C. The datasheet is rather poor and obviously inaccurate
23	on several points including this one.
25	All temperature values are given in degrees Celsius. Resolution
26	is 1.0 degree. See the datasheet for details.
28	The w83l785ts driver will not update its values more frequently than
29	every other second; reading them more often will do no harm, but will
30	return 'old' values.
32	Known Issues
33	------------
35	On some systems (Asus), the BIOS is known to interfere with the driver
36	and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable,
37	we don't really know. The driver will retry a given number of times
38	(5 by default) and then give up, returning the old value (or 0 if
39	there is no old value). It seems to work well enough so that you should
40	not notice anything. Thanks to James Bolt for helping test this feature.
