Please, can anyone from MediaTek comment on that?

I see a mt6360_pins on PIO:
			pinmux = <PINMUX_GPIO17__FUNC_GPIO17>,
				 <PINMUX_GPIO128__FUNC_GPIO128>;

...and that's GPIO128, which may effectively be the IRQ pin for MT6360.

Still, I'm not sure whether the interrupt is on GIC or PIO, please clarify,
otherwise we will have to get this commit upstream.

Thanks,
Angelo
