    Only if you're looking at very basic boards - as soon as you start
    adding any external components on the boards like speaker amps, start
    handling jacks (with detection or without) or start dealing with more
    flexible CODEC devices with a wider range of connection possibilities
    the number of possibilities expands dramatically.

    Reusing code where there's similiarities is fine - Tegra is doing that
    for WM8903 based systems in a fairly tasteful fashion - but that's not
    really what this stuff feels like it is doing. For example, the SPORT
    selection and reset GPIO selection should be platform data not Kconfig
    options and drivers that explicitly say they're for a particular board
    in Kconfig should probably say so in code also.
