    Subjectgpiolib: irq functions not implemented on x86
    Hi,

    I wrote a gpiolib implementation for Technologic Systems TS-5500 boards (x86)
    custom GPIO lines. Some of their GPIO lines are directly hooked to CPU (ElanSC520)
    GPIRQ lines, so they can trigger IRQs.

    However, looking at arch/x86/include/asm/gpio.h:
    /*
    * Not implemented, yet.
    */
    static inline int gpio_to_irq(unsigned int gpio)
    {
    return -ENOSYS;
    }

    gpio_to_irq()/irq_to_gpio() are not defined on x86 yet.

    Q: Is there a reason not to have it call gpiolib's __gpio_to_irq(), as done
    for other gpiolib functions defined here ? such as

    - return -ENOSYS;
    + return __gpio_to_irq(gpio);


    Thanks
    Jerome Oufella
