FWIW, I've posted up both a pull request in git hub to add missing
descriptions into dt-schema [1] and a patch against the kernel
repository to delete the old .txt file [2].

I'm still waiting for responses to other patches in this series before
sending a v2. When I send v2 I'll drop this patch from the series so
we can track it separately. :-)
