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 <krzk@kernel.org>
Acked-by: Jonathan Cameron <redacted> Or I can pick this up through the IIO tree if that makes sense. I doubt anything else will touch this binding this cycle, so either way works for me. Jonathan
