Thanks for the rebase. I wonder, though, I recall to had more
complicated issues. However...

I really want to see those patches go upstream, too. But I am also not a
big fan of delivering the user something with known issues. Especially
not when they affect the main feature to be added. My rationale here is
that someone who is able to fix the issues remaining will also be able
to pick up and apply patches.

Maybe, maybe if it was to be enabled by a special
I2C_AT91_SLAVE_EXPERIMANTEL symbol with lots of explanations. I need to
think twice about that, though.

Speaking of Kconfig, I think this series needs to place a

	select I2C_SLAVE

somewhere.
