Hello All,
In my device tree blob, i would like to add some interrupt to the

In the above DTS file, i would like to add the other interrupts to
the

If you use the pic-no-reset property, you don't need protected-sources
at all, unless you specifically want the error checking aspect of it.
I hope we need to use the device fdt APIs. Could you please any
pointers
or reference for how to use those APIs in the u-boot ?
fdt_appendprop looks like a good choice if you still want to do this.
