That's a bit more involved than you might think, considering we aren't

How's this?
patternProperties:
"^pci@":
$ref: /schemas/pci/pci-bus.yaml#
type: object
description: A single PCI root port
properties:
reg:
maxItems: 1
pwren-gpios:
description: Optional GPIO to power on the device
maxItems: 1
required:
- reset-gpios
- interrupt-controller
- "#interrupt-cells"
- interrupt-map-mask
- interrupt-map
