Merge tag 'i2c-for-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Mostly DT bindings additions this time because Andi was super busy and
  I also could only partly cover it.

   - new ids for qcom-cci, mt65xx, exynos5, apple, tegra20, k1, i801

   - drop support for already removed S3C2410

   - introduce and use fwnode_for_each_child_node_scoped()

   - mmt65xx: improve write-then-read transactions

   - k1: various fixes around bus errors and resets

   - usual share of cleanups, minor improvements, PM fixes...

  at24 updates:

   - add the compatible for Giantec GT24C256C to the device-tree
     bindings"
