Please make your commit message start by describing the problem you're
solving, then provide a technical description of the change.

The problem statement can mention that you consolidated the functions in
the driver, but did not update the binding before it was merged. And for
a DeviceTree binding, it should document why this
non-backwards-compatible change is okay (such as the initial commit is
broken).

Regards,
Bjorn
