    Changes for v3:
    - As suggested by Samuel Holland:
    - changed binding to gpio-fan
    - changed widgets to DACL and DACR to describe audio routing
    - fixed indentation
    - primary author of the commit should be the first signer

    Changes for v2:
    - Add missing compatible string
    - insert missing signatures of contributors
