Fixes the following problem reported by dtbs_check: envelope-detector-mux: channels: ['', '', 'sync-1', 'in', 'out', 'sync-2', 'sys-reg', 'ana-reg'] has non-unique elements arch/arm/boot/dts/at91-tse850-3.dt.yaml Suggested-by: Rob Herring Signed-off-by: Peter Rosin Acked-by: Rob Herring Signed-off-by: Jonathan Cameron --- diff --git a/Documentation/devicetree/bindings/iio/multiplexer/io-channel-mux.yaml b/Documentation/devicetree/bindings/iio/multiplexer/io-channel-mux.yaml index 80b6229a6fad8..611ad4444cf0c 100644 --- a/Documentation/devicetree/bindings/iio/multiplexer/io-channel-mux.yaml +++ b/Documentation/devicetree/bindings/iio/multiplexer/io-channel-mux.yaml @@ -35,9 +35,10 @@ properties: mux-control-names: true channels: - $ref: /schemas/types.yaml#/definitions/string-array + $ref: /schemas/types.yaml#/definitions/non-unique-string-array description: - List of strings, labeling the mux controller states. + List of strings, labeling the mux controller states.
