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.
Well, in the I2C support from menuconfig I selected the following options:
<*> I2C support --->
<*> I2C device interface
I2C Hardware Bus Support --->
<*> IMX I2C interface
Should I just select I2C support and then use sysfs as you suggested before?
Could this be the reason why my I2C adapter isn't
instantiated?

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.
