The raspberrypi,bcm2835-firmware devices requires a dma-ranges property, and, as a result, also needs to specify #address-cells and #size-cells. Those properties have been added to thebcm2835-rpi.dtsi in commits be08d278eb09 ("ARM: dts: bcm283x: Add cells encoding format to firmware bus") and 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations"), but the DT bindings haven't been updated, resulting in validation errors: arch/arm64/boot/dts/broadcom/bcm2711-rpi-4-b.dtb: firmware: '#address-cells', '#size-cells', 'dma-ranges', 'gpio' do not match any of the regexes: 'pinctrl-[0-9]+' from schema $id: http://devicetree.org/schemas/arm/bcm/raspberrypi,bcm2835-firmware.yaml# Fix this by adding the properties to the bindings.
