Hello,
I created a device node for gpio-controller for evaluation board
mpc83313erdb. I created the dtb and loaded on target.
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@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
