Merge branch 'i2c/for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"This 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"
