Correct. You have to figure out why your I2C adapter isn't
instantiated. This isn't exactly on-topic on this mailing list...

You claim you'd use i2c-imx, how do you know? Did you actually build
that driver? If it is modular, did you load the module?  Which machine
model are you using? i2c-imx is a platform driver, so the i2c-imx
device must be instantiated explicitly by the machine init code.

If you can't figure it out, it might be better to ask on list dedicated
to arm or even imx if there's one.
