Here is the second version of the patch series to describe i2c adapter quirks
in a generic way. For the motivation, please read description of patch 1. This
is still RFC because I would like to do some more tests on my own, but I need
to write a tool for that. However, I'd really like to have the driver authors
to have a look already. Actual testing is very much appreciated. Thanks to the
Mediatek guys for rebasing their new driver to this framework. That helps, too!

The branch is also here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/quirks

Thanks,

   Wolfram

Major changes since V1:

* more fine-grained options to describe modes with combined messages.
  This should also cover the Mediatek HW now as well as all other
  permutations I can think of.

* the core code and at91 driver had to be refactored to reflect the
  above change

* added the bcm-iproc driver which came to mainline recently
