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
