I wasn't aware of devres before, but I just read through the doc. It
looks interesting, and if I were writting a new driver, then I might
use it.

But for this driver, it really isn't very complex. It only looks that
way, but I think this just accidental. I guess that the code was
adapted from the davinci emac driver.

Thanks,
Richard
