Yes. Just powering it up is enough for most application.

Ok, I'll try to implement a dummy i2c driver at the same time too. I can
not test anything related to it because I do not have a piece of HW with
tfp410 i2c wires connected, but it should not matter as long as I am
able to probe it as a i2c client.
