Linus,
here is the 4.9 pull request from I2C including:
* centralized error messages when registering to the core
* improved lockdep annotations to prevent false positives
* DT support for muxes, gates, and arbitrators
* bus speeds can now be obtained from ACPI
* i2c-octeon got refactored and now supports ThunderX SoCs, too
* i2c-tegra and i2c-designware got a bigger bunch of updates
* a couple of standard driver fixes and improvements
Please pull.
Thanks,
Wolfram
