Why do you need to retrieve this? It's normally done through INTRNG.

D7579 uses this to retrieve iparent and PIC dev to be able to call PIC_* methods.

Shouldn't this be phandle_t?

My only concern is if we can move this part of code to another file, like gicv3_fdt, where we have xref stuff already. In the present shape it fails to compile when FDT support is disabled.

Move xref registration to gic_v3_fdt.c
