So I tried your suggestion and passed NULL as the pdata argument, e.g.,

...
ret = da8xx_register_i2c(0, NULL);
...

and the kernel locks up during initialization.  Did I not understand
what you were suggesting?  I will back this suggestion out until I get a chance
to hunt down the problem.  I see no other boards initialize the i2c this
way (they explicitly provide a structure).

Thanks.
