Re: [PATCH v5 1/2] dt-bindings: phy: add bcm63xx-usbh bindings

["Álvaro Fernández Rojas" <noltari@gmail.com>]

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):

Best regards,
Álvaro.
