I know this is in the changelog, and not the commit message, so you're
saying what you changed and not the reasoning for doing something, but
it'd be good to mention why the interrupt is required for this one device
only in the commit message (and since this is a binding, that
explanation needs to be something rooted in how the hardware works).

This all goes below the --- line.

Cheers,
