One can make a mistake in path when overriding. For example we have:
exynos4.dtsi:
/ {
gic: interrupt-controller@10490000 {
...
};
}
and someone can add in child dtsi (like exynos4210.dtsi):
/ {
soc {
interrupt-controller@10490000 {
cpu-offset = <0x8000>;
}
}
}
or he can make a mistake in address.
As a result the gic node won't be properly overridden.

They are overridden by child DTSI. First definition is in exynos4.dtsi
and exynos4210.dtsi adds a cpu-offset.
