Subject: [PULL REQUEST] i2c-for-6.16-rc1
Linus,
this pull-request will have a merge conflict with the media-tree. You
can find a resolution from the author of the I2C changes here [1]. The
diff there is mangled, sadly. I already asked for a better version. Hope
it arrived when you process this request.
Please pull,
Wolfram

i2c: Use str_read_write() helper (2025-05-23 17:28:07 +0200)
----------------------------------------------------------------
i2c-for-6.16-rc1
i2c-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
i2c-host updates
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)
