Regarding Level/Edge of Interrupt sense values

[Vijay Nikam]

Hello,

I created a device node for gpio-controller for evaluation board
mpc83313erdb. I created the dtb and loaded on target and the interrupt
is generated successfully.

But in dts at interrupts = <74 0x2> I set sense as Edge (sense== 2:
Edge, high-to-low change),  when I load the driver module and checked
the entry in /proc/interrupts it shows the sense as Level i.e. 8
(sense == 8: Level, low assertion) as follows;

74:          1   IPIC   Level     gpio

Following is gpio-controller device tree node;

gpio-controller at c00 {
		#gpio-cells = <2>;
		compatible = "fsl,mpc8313-gpio", "fsl,mpc8349-gpio";
		reg = <0xc00 0x100>;
		interrupts = <74 0x2>;
		interrupt-parent = <&ipic>;
		gpio-controller;
                              };

Could anyone please tell what could be the reason ? ? ? Am I missing
something ? ? ?

Kindly please acknowledge ... thank you ...

Kind Regards,
Vijay Nikam
