Linus,

the pull request for I2C contains two bigger than usual tree-wide
changes this time. They all have proper acks, caused no merge conflicts
in linux-next where they have been for a while. They are namely:

* to-gpiod conversion of the i2c-gpio driver and its users
(touching arch/* and drivers/mfd/*)

* adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)

Other notable changes:

* i2c_boardinfo can now carry a dev_name to be used when the device is
created. This is because some devices in ACPI world need fixed names
to find the regulators.

* the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.

* at24 driver has way better OF support. And it has a new maintainer.
Thanks Bartosz for stepping up!

The rest is regular driver updates and fixes.

Please pull.

Thanks,

Wolfram
