Revision 3314, 0.9 KB (checked in by frodo, 15 years ago)

Initial CVS commit of the new i2c project

Several things have changed compared to previous versions of Simon's
package. Please read IMPORTANT_CHANGES for more information.

It should compile and install again as a separate project. It will *not*
work (yet) in the lm_sensors tree.

The file INSTALL has not yet be written; but if you want to use this, please
examine the top of the Makefile, and issue `make all' followed by
`make install' (regardless of the build system used).

There are now two build systems: the old one, which needs write-access
to the kernel tree, and a lm_sensors-like one, which does not. You can
select them at the top of the main Makefile.

The patches we applied in the lm_sensors project to the i2c code have
not yet been applied.

Please examine the package, and offer comments where needed, especially
regarding changes made.
