Pull i2c-embedded changes from Wolfram Sang:
"The changes for i2c-embedded include:
- massive rework of the omap driver
- massive rework of the at91 driver. In fact, the old driver gets
removed; I am okay with this approach since the old driver was
depending on BROKEN and its limitations made it practically
unusable, so people used bitbanging instead. But even if there are
users, there is no platform_data or module parameter which would
need to be converted. It is just another driver doing I2C
transfers, just way better. Modifications of arch/arm/at91 related
files have proper acks from the maintainer.
- new driver for R-Car I2C
- devicetree and generic_clock conversions and fixes
- usual driver fixes and changes.
The rework patches have come a long way and lots of people have been
involved in creating/testing them. Most patches have been in
linux-next at least since 3.6-rc5. A few have been added in the last
week, I have to admit.
An unexpected (but welcome :)) peak in private life is the cause for
that. The "late" patches shouldn't cause any merge conflicts and I
will have a special eye on them during the stabilization phase. This
is an exception and I want to have the patches in place properly in
time again for the next kernels."
