From 3b17dd220432379dcacd89ab8836a0efc42c5b9a Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 10 Sep 2020 18:19:32 +0200 Subject: [PATCH] dt-bindings: iio: adc: exynos-adc: require second interrupt with touch screen The ADC in S3C/S5P/Exynos SoCs can be used also for handling touch screen. In such case the second interrupt is required. This second interrupt can be anyway provided, even without touch screens. This fixes dtbs_check warnings like: arch/arm/boot/dts/s5pv210-aquila.dt.yaml: adc@e1700000: interrupts: [[23], [24]] is too long Signed-off-by: Krzysztof Kozlowski Reviewed-by: Rob Herring Acked-by: Jonathan Cameron Link: https://lore.kernel.org/r/20200910161933.9156-1-krzk@kernel.org Signed-off-by: Jonathan Cameron --- .../devicetree/bindings/iio/adc/samsung,exynos-adc.yaml | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/iio/adc/samsung,exynos-adc.yaml b/Documentation/devicetree/bindings/iio/adc/samsung,exynos-adc.yaml index cc3c8ea..17a08be 100644 --- a/Documentation/devicetree/bindings/iio/adc/samsung,exynos-adc.yaml +++ b/Documentation/devicetree/bindings/iio/adc/samsung,exynos-adc.yaml @@ -41,7 +41,10 @@ properties: maxItems: 2 interrupts: - maxItems: 1 + description: + ADC interrupt followed by optional touchscreen interrupt. + minItems: 1 + maxItems: 2 "#io-channel-cells": const: 1 @@ -107,6 +110,15 @@ allOf: items: - const: adc + - if: + required: + - has-touchscreen + then: + properties: + interrupts: + minItems: 2 + maxItems: 2 + examples: - | adc: adc@12d10000 { -- 2.7.4
