Subject: [GIT PULL] i2c-host for v6.16
Hi Wolfram,
Here is a relatively small pull request for 6.16. It mainly
includes cleanups, refactorings, some driver improvements, new
bindings and just one new driver.
A few patches intended for this merge window arrived in the past
couple of weeks, but I chose to leave them out for now. If they
mature and get enough testing, I may send a part 2 pull request
next week. Perhaps I am being a bit too cautious, but because I
have experienced a few build issues this release cycle, I want to
improve the flow and avoid avoidable mistakes.
I wish you a great weekend,
Andi

----------------------------------------------------------------
i2c-host updates for v6.16
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

- 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:
