As I already wrote you for v7, quality is out of 1024, not 1000, so this
won't hit 90% as you intend.
But also, I think putting this in the DT is a mistake. Other drivers
don't generally do this, and if the hardware is actually the same piece
to piece (it is...), then there's not per-manufactured unit tweaking
needed. So keep this in the actual driver C like other drivers.
