It worked at one point. During some previous iteration, they lit up as
they were supposed to.

For a released version of the kernel? Or during development work?  If
they did work, but broken, it would be good to know which commit broke
it. We can then add a fixes: tag to the patch as proposed.

During development work. The bindings / driver was never released.
