From f89ff2b356f01e6789d48f1f58cf537d670303b7 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Fri, 17 Dec 2021 11:54:01 +0200 Subject: [PATCH] dt-bindings: iio: adc: atmel,sama5d2-adc: make atmel,trigger-edge-type non-mandatory The atmel,trigger-edge-type was never imposed by the driver. Make things right and remove this property from the mandatory list. This will not break existing nodes because according to the binding they should have this property. However, the driver does not impose it and it works without it, the property selects the trigger type, and without it, the driver will have no trigger available, which is the case on some boards which do not have access to the trigger pin. This will avoid generating this warning for example: */arch/arm/boot/dts/at91-sama7g5ek.dt.yaml: adc@e1000000: 'atmel,trigger-edge-type' is a required property From schema: */Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml Signed-off-by: Eugen Hristev Acked-by: Rob Herring Link: https://lore.kernel.org/r/20211217095401.583821-1-eugen.hristev@microchip.com Signed-off-by: Jonathan Cameron --- Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml | 1 - 1 file changed, 1 deletion(-) diff --git a/Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml b/Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml index efed361215b4..482d80dd43b5 100644 --- a/Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml +++ b/Documentation/devicetree/bindings/iio/adc/atmel,sama5d2-adc.yaml @@ -72,7 +72,6 @@ required: - atmel,min-sample-rate-hz - atmel,max-sample-rate-hz - atmel,startup-time-ms - - atmel,trigger-edge-type examples: - |
