Yes, exactly 6 interrupts. As I describe before:
- There are 22 GPIO_DSs.
- Only 6 GPIO_DSs from 0x08..0xD which supports interrupts

Hi Arnd,
Per Linus, shall we hold this driver until the GIC submission complete
? Or we will send the version without access GIC to read status in
case the GPIO is configured IRQ ?
