查看了i2c_omap.c 驱动，好像只支持master mode，平台上也很好介绍到slave mode，
从这里e2e.ti.com/.../34910我以为找到了可以解决的办法，
Hi Youssef,
spontaneously I haven't found the 2.6.29-rc3-omap1 kernel source code - so a driver patch might break because of little differences between your actual kernel and my version. I have adapted my current driver version to the interfaces provided by the 2.6.29-omap1 driver (which are probably / hopefully compatible to your rc3-version). You can download the driver file, a little application example and a readme from www-user.tu-chemnitz.de/.../i2c_omap_slave.tar.gz . Just try whether it compiles without errors... If you notice a bug please post again
但是时间关系，文件已经找不到了。所以我想这个社区里面能够提供帮助的。在此非常感谢了。
