Linus,

I2C has for you:

* API for late atomic transfers (e.g. to shut down via PMIC). We have a
seperate callback now which is called under clearly defined
conditions. In-kernel users are converted, too.
* new driver for the AMD PCIe MP2 I2C controller
* large refactoring for at91 and bcm-iproc (both gain slave support
due to this)
* and a good share of various driver improvements anf fixes

Please pull.

Thanks,

Wolfram
