    gpio: mmio: Make pin2mask() a private business · 24efd94b

    The vtable call pin2mask() was introducing a vtable function call
    in every gpiochip callback for a generic MMIO GPIO chip. This was
    not exactly efficient. (Maybe link-time optimization could get rid of
    it, I don't know.)
    
    After removing all external calls into this API we can make it a
    boolean flag in the struct gpio_chip call and sink the function into
    the gpio-mmio driver yielding encapsulation and potential speedups.
