Some I2C devices have multiple addresses assigned, for example each address
corresponding to a different internal register map page of the device.
So far drivers which need support for this have handled this with a driver
specific and non-generic implementation, e.g. passing the additional address
via platform data.
This raises the first question for me: Are the additional addresses
configurable? Sadly, I can't find good documentation for the adv7604.
Otherwise, if I know I have a adv7604 and know its addresses, this
information should go into the driver and not the DT.
They are. The current driver hard codes the other addresses, but that's not
working when you have multiple adv7604s on the same I2C bus.
