Merge tag 'i2c-for-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Core updates:
   - move towards using the 'fwnode' handle instead of 'of_node'
     (meaning 'of_node' even gets removed from i2c_board_info)
   - add support for Write Disable-aware SPD eeproms
   - minor stuff (use new helpers, typo fixes)

  i2c-atr (address translator) updates:
   - support per-channel alias pools
   - added support for dynamic address translation (also adds FPC202
     driver as its user)
   - add 'static' and 'passthrough' flags

  Cleanups and refactorings
   - Many drivers switched to dev_err_probe()
   - Generic cleanups applied to designware, iproc, ismt, mlxbf,
     npcm7xx, qcom-geni, pasemi, and thunderx
   - davinci: declare I2C mangling support among I2C features
   - designware: clean up DTS handling
   - designware: fix PM runtime on driver unregister
   - imx: improve error logging during probe
   - lpc2k: improve checks in probe error path
   - xgene-slimpro: improve PCC shared memory handling
   - pasemi: improve error handling in reset, smbus clear, timeouts
   - tegra: validate buffer length during transfers
   - wmt: convert binding to YAML format

  Improvements and extended support:
   - microchip-core: add SMBus support
   - mlxbf: add support for repeated start in block transfers
   - mlxbf: improve timer configuration
   - npcm: attempt clock toggle recovery before failing init
   - octeon: add support for block mode operations
   - pasemi: add support for unjam device feature
   - riic: add support for bus recovery

  New device support:
   - MediaTek Dimensity 1200 (MT6893)
   - Sophgo SG2044
   - Renesas RZ/V2N (R9A09G056)
   - Rockchip RK3528
   - AMD ISP (new driver)"
