If I add "additionalProperties: false" I get the following error:
/home/noltari/workspace/linux/Documentation/devicetree/bindings/pinctrl/brcm,bcm6328-pinctrl.example.dt.yaml: pinctrl@18: serial_led-pins: 'serial_led_clk-pins', 'serial_led_data-pins' do not match any of the regexes: 'pinctrl-[0-9]+'
From schema: /home/noltari/workspace/linux/Documentation/devicetree/bindings/pinctrl/brcm,bcm6328-pinctrl.yaml
