If so, this is really something different than repeated start. By using I2C_FUNC_I2C a user expects repeated start, so if the HW does not support it, we should say so and don't try to emulate it with something different. > If you think DT entry is not the way to go, do you think a CONFIG option or > something better will work? No, check at runtime if the transfer is possible on this HW.

The user should not need to know with this level of detail if we can avoid it IMO.
