Yes, that's probably what I'll end up to do (I hope to be able to do it
from kernel config file, via options). In my case I noticed that the
tda19988 is not the only thing on this I2C bus, there's also the power
controller and an eeprom at last (and probablty more via capes).
So I ended up attaching it to iic, and I'll have a way for tifb to find
it and callback to it.
