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"
