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. > El 10 jul 2020, a las 0:11, Rob Herring <robh@xxxxxxxxxx> escribió: > > On Fri, Jun 19, 2020 at 12:00:34PM +0200, Álvaro Fernández Rojas wrote: >> Document BCM63xx USBH PHY bindings. >> >> Signed-off-by: Álvaro Fernández Rojas <noltari@xxxxxxxxx> >> Reviewed-by: Florian Fainelli <f.fainelli@xxxxxxxxx> >> --- >> v5: no changes. >> v4: conditionally require 1/2 clocks and fix clock/reset values. >> v3: no changes. >> v2: phy-cells changed to 1. >> >> .../bindings/phy/brcm,bcm63xx-usbh-phy.yaml | 84 +++++++++++++++++++ >> 1 file changed, 84 insertions(+) >> create mode 100644 Documentation/devicetree/bindings/phy/brcm,bcm63xx-usbh-phy.yaml >> >> diff --git a/Documentation/devicetree/bindings/phy/brcm,bcm63xx-usbh-phy.yaml b/Documentation/devicetree/bindings/phy/brcm,bcm63xx-usbh-phy.yaml >> new file mode 100644 >> index 000000000000..f267da6193a9 >> --- /dev/null >> +++ b/Documentation/devicetree/bindings/phy/brcm,bcm63xx-usbh-phy.yaml >> @@ -0,0 +1,84 @@ >> +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) >> +%YAML 1.2 >> +--- >> +$id: "http://devicetree.org/schemas/phy/brcm,bcm63xx-usbh-phy.yaml#" >> +$schema: "http://devicetree.org/meta-schemas/core.yaml#" >> + >> +title: BCM63xx USBH PHY >> + >> +maintainers: >> + - Álvaro Fernández Rojas <noltari@xxxxxxxxx> >> + >> +properties: >> + compatible: >> + enum: >> + - brcm,bcm6318-usbh-phy >> + - brcm,bcm6328-usbh-phy >> + - brcm,bcm6358-usbh-phy >> + - brcm,bcm6362-usbh-phy >> + - brcm,bcm6368-usbh-phy >> + - brcm,bcm63268-usbh-phy >> + >> + reg: >> + maxItems: 1 >> + >> + clocks: >> + maxItems: 1 >> + >> + clock-names: >> + const: usbh >> + >> + resets: >> + maxItems: 1 >> + >> + "#phy-cells": >> + const: 1 >> + >> +required: >> + - compatible >> + - reg >> + - clocks >> + - clock-names >> + - resets >> + - "#phy-cells" > > You need: > > additionalProperties: false > >> + >> +allOf: >> + - if: >> + properties: >> + compatible: >> + enum: >> + - brcm,bcm6318-usbh-phy >> + - brcm,bcm63268-usbh-phy >> + then: >> + properties: >> + clocks: >> + maxItems: 2 > > This doesn't work.
