mpc5200 interrupts have three cells in the device tree. How are these
interpreted?
Middle one is the interrupt number. Last one seems to always be zero.
What does the first one do, edge/level?

I searched through /Documentation and could find anything about three
cells for interrupts.

I understand the first one for gpio_wkup on interrupt 8. How does a
gpio_wkup generate an interrupt on interrupt 3?

		gpio_wkup: gpio-wkup@c00 {
			compatible = "fsl,mpc5200b-gpio-wkup","fsl,mpc5200-gpio-wkup";
			reg = <0xc00 0x40>;
			interrupts = <0x1 0x8 0x0 0x0 0x3 0x0>;
			interrupt-parent = <&mpc5200_pic>;
			gpio-controller;
			#gpio-cells = <2>;
		};
