My mistake -- sorry. Also sorry for getting your name wrong repeatedly.

In "i2c-davinci: Fix race when setting up for TX" and "i2c-davinci:
Fix TX setup for more SoCs" you mention testing on DM355 -- is there

occasion and that you would be available to test modifications to the
current implementation?

:) Probably not then.
