Merge branch 'i2c/for-mergewindow' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- core supports now bus regulators controlling power for SCL/SDA
- quite some DT binding conversions to YAML
- added a seperate DT binding for the optional SMBus Alert feature
- documentation with examples how to deal with I2C sysfs files
- some bigger rework for the i801 driver
- and a few usual driver updates
