I2C总线LINUX驱动程序

This package includes the basic i2c drivers.
This package is ONLY for 2.4 kernels 2.4.10 or later!

FOR 2.5/2.6 KERNELS, Do not attempt to compile this package.
                 Use the drivers already in the 2.5/2.6 kernel tree.

=============================================================================

There are basically two kinds of i2c drivers: drivers for busses and drivers
for chips. Both are cut in two, to isolate common parts: bus drivers are
separated into algorithm drivers and adapter drivers, and chip drivers
are separated into `driver' drivers and client drivers.

This package contains all the basic i2c code, as well as a few bus drivers
(both the algorithm and the adapter drivers). There are no real chip
drivers, so on its own it is not very useful. Lots of chip drivers, as
well as more bus drivers and some additional basic code
(for SMBus emulation over i2c) and some i2c debugging tools
are found in the lm_sensors package at http://www.lm-sensors.nu.
Another place at which I2C is used is the video4linux project.

See doc/summary for a description of the drivers in this package.

2.4 KERNELS USING OTHER I2C DRIVERS (BTTV AND THE SUCH)
-------------------------------------------------------
i2c 2.8.x were not compatible with earlier i2c releases due to struct
changes. This was fixed and i2c 2.9.0 and later are compatible with
older i2c implementations, including the one present in 2.4 kernels
since 2.4.13. i2c (and lm_sensors) can again be compiled outside of the
kernel tree.

If you still want to patch your kernel tree with this version of i2c
(e.g. to builf a non-modular kernel), a complete installation guide is
available at
  http://khali.linux-fr.org/devel/i2c/
In particular, kernels 2.4.23 to 2.4.28 will require an additional patch
fixing a minor incompatibility between 2 drivers (bttv and tvmixer) and
i2c 2.9.0 and later.
