interrupt-parent is not to be used as a boolean property.
It is already present in the DT in the proper way it's supposed to be used:
interrupt-parent = <&gic>;

This is also reported by dtbs_check:
arch/arm/boot/dts/at91-sama7g5ek.dtb: interrupt-controller@e8c11000: interrupt-parent: True is not of type 'array'
	From schema: /.local/lib/python3.8/site-packages/dtschema/schemas/interrupts.yaml

Fixes: 7540629e2fc7 ("ARM: dts: at91: add sama7g5 SoC DT and sama7g5-ek")
