I doubt anything else will touch this binding this cycle, so either way works for me.

Let's wait for Rob's review and then if you could, please pick it up. Best regards, Krzysztof

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.
