    SubjectRe: [PATCH 2/6] [media] Documentation: Add HSV format
    Hi Ricardo,

    I'm not seeing patch 1.

    Anyway, please send documentation patches against the rst files. They're
    at the "docs-next" branch and will be merged upstream on this merge window.

    After its merge, we'll drop the DocBook.

    Thanks,
    Mauro
