linux3.0.1 外部中断GROUP1~9无法request_irq
想在GPP1口上设置一个外部中断尝试将按键驱动中的S3C64XX_GPN，换成S3C64XX_GPP，但无法申请中断成功
只有对应的gpio口为GROUP0时方可申请成功，
linux-3.0.1\arch\arm\mach-s3c64xx中只有irq-eint.c,没有关于group的定义
求各位大神看看应该怎么改
/* gpio buttons */
static struct gpio_keys_button gpio_buttons[] = {
{
.gpio = S3C64XX_GPN(0),
//.code = 25,
.code = KEY_UP,
.desc = "BUTTON1",
.active_low = 1,
.wakeup = 0,
}
,
{
.gpio = S3C64XX_GPP(1),
//.code = 42,
.code = KEY_DOWN,
.desc = "BUTTON2",
.active_low = 1,
.wakeup = 0,
}/*
}
