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"
