You need:

additionalProperties: false

This doesn't work. The main schema will also be applied and it says 
there's 1. The main schema has to cover all the cases and then if/then 
schemas add constraints.

Hi Rob,

If adding "additionalProperties: false” throws the following error, which I don’t understand:
/home/noltari/workspace/linux/Documentation/devicetree/bindings/phy/brcm,bcm63xx-usbh-phy.example.dt.yaml: usb-phy@10001700: 'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+’

BTW, is this what you mean? (I added another if section for the cases with just 1 clock):
https://gist.github.com/Noltari/9bd94a30e8bcc857d6af87985d7ca010

Best regards,
Álvaro.
