After merging the broadcom tree, today's linux-next build (arm

This is expected. My commit ef126d3f58d25 ("ARM: dts: BCM5301X: Add
basic PCI controller properties") reduced following warnings:
arch/arm/boot/dts/bcm47081-buffalo-wzr-600dhp2.dtb: pcie@12000: 'device_type' is a required property

down to this one:
arch/arm/boot/dts/bcm47081-buffalo-wzr-600dhp2.dtb: pcie@12000: 'ranges' is a required property
From schema: /lib/python3.9/site-packages/dtschema/schemas/pci/pci-bus.yaml
and basically does the right thing (adds required properties).
I'm fully aware "ranges" need to be added (it's mentioned in the commit)
and it's one of next things on my BCM5301X list.
So while my commits triggers that problem it also reduces warnings so
I'd say it's acceptable.
