I have one other general comment: it is a bit confusing at the moment
which parts of the driver are adv7604 specific, adv7611 specific or common
for both.
It might be a good idea to create a separate patch that renames any adv7604
prefixes (both for functions and defines) to adv76xx whenever they are common.
