From: Conor Dooley <conor.doo...@microchip.com> When optional AIA PLIC support was added the to the virt machine, the address cells property was removed leading the issues with dt-validate on a dump from the virt machine: /stuff/qemu/qemu.dtb: plic@c000000: '#address-cells' is a required property From schema: /stuff/linux/Documentation/devicetree/bindings/interrupt-controller/sifive,plic-1.0.0.yaml Add back the property to suppress the warning.
