If the format resembles the existing formats but on a different bit depth,
it should be named in similar fashion.
Could you also add ReST documentation for the format, please?
The common requirement for merging patches that change interfaces has been
that there's a user for that change. It'll still help you to get this
reviewed now so the interface that the future hopefully-in-mainline driver
provides will not change.
