    gpiolib: Pass bitmaps, not integer arrays, to get/set array · b9762beb
    Janusz Krzysztofik authored
    Most users of get/set array functions iterate consecutive bits of data,
    usually a single integer, while processing array of results obtained
    from, or building an array of values to be passed to those functions.
    Save time wasted on those iterations by changing the functions' API to
    accept bitmaps.
    
    All current users are updated as well.
    
    More benefits from the change are expected as soon as planned support
    for accepting/passing those bitmaps directly from/to respective GPIO
    chip callbacks if applicable is implemented.
