I have no idea that we need specific interrupt on EXYNOS4 now.
As you know, this can affect all machines of EXYNOS4 SoC even though there
is EXYNOS4210 now.
If required, we need something like SAMSUNG_GPIO_EXTRA for compatibility.
Anyway need more discussion on this :)
Thanks.
Best regards,
Kgene.

Now pmic8998, 8997 requires extra interrupts.
If you don't want to extends irqs, the sparse irq can be used at each board.
Of course, in case of exynos4210, need some patch for sparse irq support.
