Merge tag 'i2c-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Browse Source 
Pull i2c updates from Wolfram Sang:
 "Core:

   - list-based mechanisms for handling auto-detected and userspace
     created clients are replaced with a flag-based approach. The
     resulting code is much simpler as well as the locking.

   - i2c clients now get a default debugfs dir managed by the I2C core.
     Drivers don't have to maintain their own directory anymore.

  Driver updates:

   - xiic: atomic_transfer support

   - imx-lpi2c: DMA and target mode support

   - riic cleanups

   - npcm: better timeout handling and more precise frequency setups

   - davinci: remove unused platform_data

   - at24: add new compatibles for variants from Giantec and Puya
     Semiconductor (together with a new vendor prefix)"
