    There was some discussion of this on the I2C list and a decision that it
    was sensible to move away from doing that since it was being found to
    cause more problems than it solved - the FSL driver is the one I
    remember actually doing so.

    Yes. Pretty much any embedded I2C driver could cause issues for the
    Wolfson drivers - there's a whole bunch of audio CODECs that are very
    widely deployed.

    Yes, it's fairly rare which is the main reason it's not being chased
    after particularly actively.
