What I want to do is that you can pass such data through the board_info.
Patch for that have been posted but I still haven't had the chance to sit
down and review them :-(
This method is the common method for existing i2c drivers and should (I
think) be used for all new i2c drivers.

You're not trying to pass register/value pairs to the i2c driver, are you?
You should tell the i2c driver what you want and let the i2c driver do the
register programming for you. Only the i2c driver should know about the
registers of the i2c device.

Use init as long as the new functions passing the board_info to the i2c
core are not yet available. You can convert once we have the new API in
place.

It's work in progress and I'm the bottleneck here :-(
