Merge tag 'i2c-for-6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c fixes from Wolfram Sang:
 "The main thing is the removal of 'probe_new' because all i2c client
  drivers are converted now. Thanks Uwe, this marks the end of a long
  conversion process.

  Other than that, we have a few Kconfig updates and driver bugfixes"

* tag 'i2c-for-6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: cadence: Fix the kernel-doc warnings
  i2c: aspeed: Reset the i2c controller when timeout occurs
  i2c: I2C_MLXCPLD on ARM64 should depend on ACPI
  i2c: Make I2C_ATR invisible
  i2c: Drop legacy callback .probe_new()
  w1: ds2482: Switch back to use struct i2c_driver's .probe()
