i2s is anoter i/o , but i read the source of i2c and
i think that the minor number is correct
Thanks for help

i created the i2c with
mknod /dev/i2c c 89 1

This is just a hunch, but is that the proper minor device number?  In my
copy of the kernel sources, in the file arch/ppc/5xxx_io/i2s.c, I see
this
definition:

#define I2S_MINOR 242

...which makes me wonder if "mknod /dev/i2c c 89 242" would work any
better.  Does your source tree include that same definition?  Is that
"minor number" the one you need to use with mknod?

I'm a novice at this Linux-on-embedded-PPC stuff, so please forgive me if
this is useless advice--and please let me know how you resolved the
problem when you find the "right" answer. :-)
