Thanks for the suggestions..
Is there any code pointers(using fdt_appendprop()) to modify/add the
interrupt numbers to the existing protected-sources property under pic
controller ?
mpic: pic@40000 {
interrupt-controller;
#address-cells = <0>;
#interrupt-cells = <2>;
reg = <0x40000 0x40000>;
compatible = "chrp,open-pic";
device_type = "open-pic";
protected-sources = <
16 , *0 , 28*
>
Any help would be greatly appreciated
Thanks,
Kamaraj
