    [media] V4L: soc-camera: make (almost) all client drivers re-usable outside of the framework · 2f0babb7
    Guennadi Liakhovetski authored
    The most important change in this patch is direct linking to struct
    soc_camera_link via the client->dev.platform_data pointer. This makes most
    of the soc-camera client drivers also usable outside of the soc-camera
    framework. After this change all what is needed for these drivers to
    function are inclusions of soc-camera headers for some convenience macros,
    suitably configured platform data, which is anyway always required, and
    loaded soc-camera core module for library functions. If desired, these
    library functions can be made generic in the future and moved to a more
    neutral location.
    
    The only two client drivers, that still depend on soc-camera are:
    
    mt9t031: it uses struct video_device for its PM. Since no hardware is
    available, alternative methods cannot be tested.
    
    ov6650: it uses struct soc_camera_device to pass its sense data back to
    the bridge driver. A generic v4l2-subdevice approach should be developed
    to perform this.
