I haven't looked at the driver yet, but your explanation in the cover letter
of why it is a separate driver seems fine.

That doesn't exclude using a shared device tree binding (as it is a many
to many relationship between bindings and drivers) and it seems like
nothing stops you combining this with the tle493d-a1b6 binding.

Thanks,

Jonathan
