Do you mean just dropping these two lines (and MaxItems: 1), and leaving "reg" in "required" and in the example? E.g.: ... required: - compatible - reg - clocks - clock-names - port additionalProperties: false examples: - | #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/clock/imx6qdl-clock.h> i2c { #address-cells = <1>; #size-cells = <0>; ar0521: camera-sensor@36 { compatible = "onnn,ar0521"; reg = <0x36>; pinctrl-names = "default"; ... It protests with: Documentation/devicetree/bindings/media/i2c/onnn,ar0521.example.dt.yaml: camera-sensor@36: 'reg' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: /usr/src/linux/imx6/Documentation/devicetree/bindings/media/i2c/onnn,ar0521.yaml Thus I'm currently leaving it as is. -- Krzysztof Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al.
