Hi,

This set of patches is based on Nikolaus at91_i2c driver.

Changes:
v3:
- only put multi-drive lines in the if...else statement (suggested by Warner Losh)

Hi Wolfram,

As said by Ludovic, this series goes on top of Nikolaus' one. My Acked-by is already set on this one, so I think that I have nothing more to do ;-)

BTW, in case you need help to sort all this, do not hesitate to contact us... we can setup a git tree for this...

Bye,
