I believe that the following patch is necessary to properly configure
GPIO line configuration for IRQ's which are mapped to a GPIO line >= 8
(without this patch the wrong GPIO is configured as an input.)

*int_reg |= (int_style << (line * IXP4XX_GPIO_STYLE_SIZE));
/* Configure the line as an input */
- gpio_line_config(line, IXP4XX_GPIO_IN);
+ gpio_line_config(irq2gpio[irq], IXP4XX_GPIO_IN);
return 0;
