Merge tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"This removes the currently unused CLASS_DDC support (controllers set
the flag, but there is no client to use it).
Also, CLASS_SPD support gets simplified to prepare removal in the
future. Class based instantiation is not recommended these days
anyhow.
Furthermore, I2C core now creates a debugfs directory per I2C adapter.
Current bus driver users were converted to use it.
Finally, quite some driver updates. Standing out are patches for the
wmt-driver which is refactored to support more variants.
This is the rebased pull request where a large series for the
designware driver was dropped"
