Hey Jackson,

just as a quick info, I feel like the title of the cover letter is a bit
confusing, as it sounds like it contains the source code for the wave5
codec driver, which we already have. Usually the title of the cover
letter should indicate to the reader what to expect in the patch-set
(which can also be a really nice indication for when you try to do too
much in a single patch-set, because then it will be hard to make a
concise title).

Greetings,
Sebastian
