+Kernel driver w83l785ts

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