Hi,
We have designed a system using a mpc8270 cpu. The firmware we
use is u-boot and we can access all our i2c devices from u-boot.
But when we try to access i2c devices from under linux 2.6 using
the /dev/i2c-0 special file we get an ENODEV on opening that
file. I think it is because we lack an adapter driver.
If I look in the official kernel, it looks like the adapter
driver for the mpc8270 i2c system is
./drivers/i2c/busses/i2c-mpc.c. Is this correct?
Why is this driver registering as a platform driver and not as a
i2c bus driver?
In DENX ELDK there is also a i2c-mpc8260.c, but we couldn't get
that to work either.
What should I do to be able to access i2c devices using the
/dev/i2c-0 file? I feel I need to modify the i2c adapter driver
to follow the driver model, but in what ways?
Thx for any help,
-jf simon
