Hi,
Using linux 2.6, I have problem with an i2c bus driver. The driver does
a driver_register() call in its init entry point.
In that process it registers a probe routine, but this one never gets
called. As a result the i2c bus is not working, since the i2c bus driver
never got a chance to register itself w/ the i2c_add_adapter() function
as described in the linux journal article:
http://www.linuxjournal.com/article/7136
Try looking at the documentation for the i2c core in Documentation/i2c/
and look at the existing i2c drivers, as the api has changed a bit since
I wrote that old article.
If you still have questions, try posting the patch on the sensors
mailing list, as that is the best place for this.
Thanks. But I believe my problem has to do with a driver model issue
more than i2c. The driver registers itself w/ driver_register() but the
subsequent probe routine never gets called. I am not sure what triggers
the probe to be called. I will keep looking in the code.
Thx
