Subject[PULL REQUEST] i2c for v5.14
Linus,

now that 5b1170560889 ("drm/i915/selftests: Rename pm_ prefixed
functions names") hit your tree, I can ask you to pull these I2C changes
for 5.14. Main items:

* 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

Please pull.

Thanks,

Wolfram
