That was what you did, not the goal. If that's the goal, then it is
clearly wrong.

Series or half-of-series? Anyway, commits must be logical chunks, so one
chunk is to add I2C controllers, not "part of I2C controllers". DTS is
also independent of drivers (and it will go via different trees!), so
whatever dependency you think of, it does not exist.
