which ensures i2c Bus is tristated correctly. It isn't clear from
the datasheet if the 586's GPIO pins are open drain or not,
but if they aren't, then the driver was driving the pins high
rather than letting them get pulled high as the spec requires.
This is corrected by toggling the direction rather than the
data register to control the bus.

lm_sensors CHANGES file
|
|
-----------------------
|
|
This is a list of the most important changes in 2.x versions. It is by
|
|
no means complete, listing only user-visible changes which are interesting.
|
|
The ultimate way to know what has changed is to run diff, or even neater,
|
|
ask CVS about it:
|
|
|
|
* Checkout the archive (see doc/cvs for how you can do this)
|
|
* Determine which tags are valid, by running this command from the
|
|
project root directory:
|
|
cvs status -v -l Makefile
|
|
Valid tags are usually like form V2-1-0 for version 2.1.0
|
|
* Ask cvs for the difference between two versions:
|
|
cvs diff -r TAG1 -r TAG2 DIFF-OPTIONS
|
|
for example:
|
|
cvs diff -r V2-0-0 -r V2-0-1 -u
|
|
